12 Crochet Phone Case Patterns with Straps You’ll Actually Want to Make
There’s something deeply satisfying about carrying a handmade phone case. It’s one of those small, everyday items that people notice — tucked under your arm at a coffee shop, dangling from your wrist at a farmer’s market, or peeking out of your tote bag on the subway. When that case is crocheted, it becomes a little wearable piece of craft that tells the world you made something with your own hands.
Crochet phone cases with straps are having a real moment right now, and honestly, it makes perfect sense. They’re practical, endlessly customizable, and quick enough to finish in a single afternoon if you pick the right pattern. The strap transforms a simple pouch into something you can carry crossbody, loop around your wrist, or clip to your bag. Whether you’re a beginner who just learned the single crochet stitch or an advanced crocheter looking for a new project between bigger pieces, there’s a phone case pattern here for you.
This roundup covers twelve of the best crochet phone case patterns with straps, organized from beginner-friendly to more involved designs. For each one, you’ll find details on the skill level, the type of yarn and hook you’ll need, what makes it special, and tips to help your finished piece look polished and professional.
Why Crochet a Phone Case Instead of Buying One?
Before we dive into the patterns, it’s worth talking about why so many people are reaching for their hooks instead of their Amazon carts. The obvious answer is customization — you can make a case in exactly the right color, exactly the right size, and with exactly the kind of strap length you prefer. But there’s more to it than that.
Handmade crochet cases are also gentler on phones than rigid plastic cases. A snug-fitting fabric pouch absorbs minor bumps and scratches without adding much bulk. When you make it yourself, you can tailor the fit precisely to your phone model rather than hoping a generic size will do.
There’s also the joy of the craft itself. A phone case is small enough that you can experiment with new stitches or techniques without committing to a sweater’s worth of yarn. Many crocheters use phone case projects to practice texture stitches, colorwork, or finishing techniques they want to apply to larger projects later.
And then there’s the gift factor. A handmade crocheted phone case is one of those presents that feels personal and thoughtful without taking weeks to make. Give one to a friend in her favorite color, and she will appreciate it far more than a store-bought case.
What You’ll Need Before You Start
Most crochet phone case patterns with straps call for a relatively small set of supplies, but getting the right materials will make a real difference in how your finished case looks and performs.
Yarn: Cotton yarn is the most popular choice for phone cases because it’s durable, holds its shape, and doesn’t stretch out the way acrylic can. Look for a fingering weight or DK weight cotton for a slim profile, or a worsted weight if you want something chunkier and more textured. Some makers love using chunky macramé cord for a boho aesthetic, while others prefer velvet yarn for a luxurious feel.
Hook size: Always match your hook to your yarn weight, but keep in mind that phone cases benefit from a slightly tighter gauge than the yarn label recommends. Going down half a size or one full size from the suggested hook creates a denser fabric that holds its shape and provides better protection for your phone.
Notions: Depending on the pattern, you might need a tapestry needle for weaving in ends, stitch markers, a small carabiner or swivel clasp for the strap attachment, a button or snap for the closure, and a ruler or measuring tape to check your gauge.
Phone dimensions: Measure your phone before you start. Most patterns are designed around a general size category (slim, standard, or large), but knowing your exact measurements helps you adjust gauge or stitch count accordingly.
The 12 Patterns
1. The Classic Single Crochet Pouch with Wrist Strap
This is the pattern you’ll want to recommend to anyone who asks where to start. It uses nothing but single crochet worked in the round, which makes it an ideal first project for someone still building confidence. The resulting fabric is dense and neat, the kind that looks intentional and handcrafted rather than beginner-made.
Work in DK weight cotton using a 3.5mm hook. Start with a foundation chain slightly narrower than your phone’s width, then join and work in continuous rounds. When the pouch reaches your phone’s height, decrease across the top to create a gentle tapered edge, then add a simple slip-stitch loop for a button closure. The wrist strap is a crocheted chain reinforced with a second row of single crochet — thin, strong, and adjustable to whatever length you prefer.
The beauty of this pattern is that it’s completely open to personalization. Work in stripes, use a variegated cotton, or add a simple surface crochet initial on the front before finishing. It takes about two to three hours and uses less than 50 grams of yarn.
2. The Ribbed Crossbody Case
If you want a case that looks polished enough to carry to work or dinner, this ribbed crossbody design delivers. The ribbing is created by working in back loops only throughout, which gives the fabric that satisfying stretchy texture you see in ribbed hats and cuffs. It hugs the phone snugly and has just enough elasticity to slip your phone in and out without a fuss.
Use a sport weight cotton in a solid color to let the texture shine. The crossbody strap is made with a long chain and reinforced with single crochet, then finished with a lobster clasp at each end for easy removal. You can make it the traditional crossbody length (around 50 to 60 inches) or shorter for an over-the-shoulder version.
A magnetic snap closure keeps everything secure without adding bulk. This project is accessible to intermediate beginners — if you’ve made a hat or a dishcloth before, you have all the skills you need.
3. The Boho Fringe Bag with Chain Strap
This one leans hard into the free-spirited aesthetic that’s been all over Pinterest and Instagram for the past few years. The body of the case is worked in half double crochet, which creates a slightly looser, airier fabric than single crochet. A row of cut fringe along the bottom adds movement and texture, and the adjustable chain strap — made from crochet-covered chain links — gives it that artisan look.
Natural cotton twine or jute yarn works beautifully here, especially if you want the finished piece to look like it came from a craft fair. The fringe can be left plain, knotted, or even beaded for extra personality. This pattern introduces a simple flap closure that folds down over the phone’s top edge, which looks intentional and adds a bit of extra protection.
Skill level sits comfortably at beginner to intermediate, and the chain strap technique is explained in most pattern write-ups with a photo tutorial, making it very approachable even if you’ve never made a strap this way before.
4. The Granny Square Phone Wallet
Granny squares are having their biggest revival in years, and this clever pattern turns two small squares into a fully functional phone wallet with card slots. The construction is simple: two squares crocheted in your chosen colorway, joined along three sides, with a folded inner pocket sewn or crocheted in for cards, cash, or a transit pass.
The strap attaches at the side seam with a small ring, and you can use a purchased crossbody chain, a crocheted cord, or even a wide strap made from multiple slip-stitched chains for a different look. Because granny squares are so iconic and recognizable, this case immediately reads as intentionally handmade and on-trend.
Use a size 4 cotton yarn (worsted weight) with a 4.5mm hook for the best structure. The colorwork is entirely up to you — classic multicolor rounds look wonderful, but a tonal or monochromatic square is equally chic.
5. The Bobble Stitch Case with Tassel Strap
Bobbles are one of those stitches that looks far more complicated than it actually is, and this case is proof. Worked in offset columns, the bobbles create a popcorn-like texture that adds significant visual interest without requiring much more effort than a standard pouch.
The tassel strap is the star of this design. Cut lengths of yarn in a contrasting or complementary color, loop them through a ring at each end of the strap, and you have a playful, festival-ready accessory. The strap itself is worked in single crochet and is completely removable, so you can swap tassels to match different outfits.
This is a great intermediate pattern for someone who’s been crocheting for a few months and wants to branch out from basic stitch patterns. The bobble technique is explained clearly in most versions of this pattern, and after the first few stitches, it becomes almost meditative.
6. The Tapestry Crochet Geometric Case
Tapestry crochet is the technique of carrying multiple colors across a row and switching between them to create colorwork patterns — similar to stranded knitting but worked in crochet. The results can be absolutely stunning, and a phone case is the perfect small canvas for a first tapestry project.
This pattern typically features a geometric or tribal-inspired motif on the front panel: chevrons, diamonds, triangles, or stylized flowers. The back is worked in a solid color to keep things simple. The strap is usually a long, narrow strip worked in one of the pattern’s accent colors, giving the whole piece a cohesive, designed look.
The difficulty here is moderate to advanced because maintaining even tension while carrying two yarns takes practice. But the payoff is a case that genuinely looks like something you’d see in a boutique shop, and the skills you pick up will open the door to tapestry crochet bags, blankets, and wall hangings.
7. The Mesh Phone Bag with Bead Detail
This ethereal little bag uses a simple mesh stitch — alternating chain spaces with single crochets — to create a delicate, see-through fabric that shows off your phone’s screen. It’s lightweight, quick to make, and surprisingly beautiful.
The bead detail is optional but worth the extra step: string beads onto your yarn before you begin and slide one into place at each chain space as you work. The effect is a lightly beaded lattice that catches the light in the most flattering way. A thin crocheted cord strap, finished with beaded ends, completes the look.
This case works best for occasions when you’re not worried about heavy-duty protection — it’s more of a fashion accessory than a drop-proof case. Use a fingering weight or crochet thread with a 1.75mm or 2mm hook for the most delicate result, or scale up to DK weight for something a bit more sturdy.
8. The Simple Slip-Stitch Bag with Adjustable Cord
Sometimes the most understated designs are the most wearable, and this minimalist slip-stitch case is a perfect example. Slip stitch fabric is dense and flat, with almost no texture, which gives it a surprisingly modern, sophisticated look. It also makes for a very durable case — slip stitch fabric is nearly impossible to pull or snag.
Work in a cotton-linen blend for the nicest drape and hand feel, or use a solid cotton in a deep jewel tone for maximum impact. The adjustable cord strap threads through two small loops at the top of the case and can be shortened or lengthened with a sliding knot. It’s elegant and functional in equal measure.
This pattern is beginner-friendly in terms of stitch complexity, but the dense fabric can be hard on your hands if you’re crocheting for extended periods. Take breaks as needed and use an ergonomic hook if slip stitch tension tends to make your grip too tight.
9. The Chunky Cable-Look Case
Cables in crochet are made using front post and back post double crochets rather than the knitting technique of crossing stitches, but the result has that same satisfying raised, twisted texture that cable knits are known for. This case features a central cable panel flanked by simple double crochet columns, all worked in a chunky cotton.
Because of the bulkier yarn, the case has real substance and padding to it — your phone will be well protected inside. A wide crocheted strap works the same front and back post technique as the body, so the whole piece feels cohesive.
This is a great project for anyone who’s been doing basic double crochet and wants to learn post stitches for the first time. The learning curve is gentle, and once the technique clicks, it becomes one of the most satisfying in all of crochet.
10. The Waffle Stitch Phone Sleeve
The waffle stitch creates a grid-like pattern of raised squares that looks remarkably like — you guessed it — a waffle. It’s a combination of single crochets, double crochets, and chain spaces worked in a specific sequence, and it produces a thick, cushiony fabric that’s excellent for phone protection.
This sleeve style (meaning open at the top with no closure) slips over your phone for quick access, with a simple wrist loop rather than a full strap. It’s the fastest version on this list — many makers finish the whole thing in under 90 minutes. If you want a closure, you can add a button loop to the top edge very easily.
The waffle stitch is beginner-accessible once you understand the pattern repeat, and it’s one of those stitches that’s genuinely enjoyable to work because you can see the texture building row by row. Use a pastel or earthy cotton for the most appealing result.
11. The Flower Motif Bag with Long Strap
This romantic design features a crocheted flower worked separately and then sewn onto the front of a simple single crochet pouch. The flower can be as simple as a basic five-petal design or as elaborate as a layered dimensional bloom — most patterns for this style include a few options at different difficulty levels.
The long strap is made from a crocheted chain worked in rows of single crochet and can be made to any length you like, from a short shoulder strap to a full-length crossbody. The closure is usually a button positioned at the center of the flower, so the bloom doubles as a decorative and functional element.
This is a lovely gift project, especially when you customize the flower color to suit the recipient. It sits at a beginner to intermediate level and typically uses under 100 grams of yarn total.
12. The Textured Colorblock Case with Removable Strap
This final pattern pulls together several of the techniques featured throughout this list into one polished, versatile design. The body of the case is divided into two or three colorblock sections, each worked in a different stitch for added texture — for instance, single crochet on the bottom third, ribbing through the middle, and a simple shell stitch at the top.
The strap is fully removable, attached with small D-ring loops at the top corners, which means you can swap it out for different lengths or colors. A simple flap closure with a magnetic snap finishes the look cleanly.
This is the kind of case that looks like you’ve been crocheting for years even if you’re still relatively new to it. The colorblocking does a lot of the visual work for you, and the mixed stitch sections are each simple enough individually that the overall project remains very manageable.
Tips for Making Your Phone Case Look Professional
No matter which pattern you choose, a few finishing habits will take your phone case from handmade to beautifully crafted. Always weave in your ends thoroughly — any loose tail that works its way out of the stitches will undermine the whole piece. Use a tapestry needle to work the tail back and forth through the fabric in different directions before trimming it close.
Block your case if possible, especially if you’re using cotton or linen. A quick damp blocking — just misting with water and laying flat to dry — evens out the stitches and gives the final piece that professional, even look you see in pattern photos.
Pay attention to your tension throughout the project. Consistent tension is the single most impactful factor in how neat your finished piece looks. If you notice your stitches getting looser as you warm up or tighter when you’re stressed, take a moment to reset.
Finally, don’t skip the finishing details. A well-chosen button, a clean lobster clasp, or a neatly trimmed tassel elevates a finished case enormously. These small details are where handmade items win over mass-produced ones every time.
Whether you’re making your first crochet phone case or your fiftieth, this collection of patterns offers something worth picking up your hook for. From the simplest single crochet pouch to the most textured colorblock design, each of these projects results in something genuinely useful, beautiful, and made entirely by your own hands. That combination is hard to beat.
