It holds your essentials — your phone, some cards, a lip balm, maybe a small set of keys — without weighing you down or cluttering up your look. And the best part? You can make one yourself in a weekend with a simple pattern, even if you are still building your crochet skills.

This free crochet crossbody phone bag pattern is designed for all skill levels.

The construction is straightforward, the materials are inexpensive and easy to find, and the finished result is something you will genuinely want to carry around all summer long.

Let us get into everything you need to know — from choosing your yarn to fastening off your last stitch and adjusting the strap to just the right length.

Why Crochet a Phone Bag This Summer

Crossbody bags have been a summer staple for years, and crochet versions have surged in popularity for good reason. They are lightweight, they breathe well in hot weather, they add texture and visual interest to any outfit, and they show off your maker skills in a way that no store-bought accessory ever could.

A crochet phone bag specifically is a practical project because it is sized to solve a real problem. How many times have you gone to a summer event carrying a full-sized tote, only to realize you only actually needed your phone and a card or two? A small crossbody keeps your hands free, stays secure across your body, and gives you that effortlessly chic boho look without any effort at all.

This pattern is also completely free, which means you can experiment with different colors and yarns without feeling like you have to commit. Make one in natural cotton for a neutral everyday look, try a bright citrus color for the pool, or use variegated yarn to let the color do all the work. There is no wrong direction.

Materials You Will Need

Before you begin, gather your supplies. The beauty of this project is that it does not require much.

Yarn: Approximately 150 to 200 yards of size 3 or 4 cotton yarn. Cotton is the ideal choice for summer bags because it holds its shape well, has a lovely drape, and stands up to wear without stretching out. Lion Brand 24/7 Cotton, Paintbox Simply DK, and Paintbox Simply Aran are all excellent choices. You can also use a jute or raffia-style yarn if you want a more natural, earthy texture.

Hook: A 4.0mm to 5.0mm crochet hook, depending on your yarn weight and your personal tension. If you tend to crochet tightly, go up a half size from what the yarn label recommends.

Notions: A tapestry needle for weaving in ends, scissors, a stitch marker or two, and an optional D-ring or swivel clasp if you want to make the strap detachable or adjustable.

Optional: A small piece of lining fabric and a sewing needle and thread if you want to add an interior lining. This is especially helpful if you plan to carry loose items like coins or earbuds.

Gauge and Sizing

Gauge: 16 stitches and 18 rows = 4 inches in single crochet using a 4.5mm hook and size 4 cotton yarn.

Gauge matters more for bags than it does for many other projects because you want the fabric to be dense enough that small items do not fall through the stitches. If your gauge is too loose, switch to a smaller hook. If it is too tight and your fabric feels stiff, go up a size.

Finished dimensions: Approximately 6.5 inches wide by 8 inches tall (not including the strap). This fits most modern smartphones comfortably, including larger models like the iPhone Pro Max or Samsung Galaxy Ultra. The bag has a little extra room for a few cards, a folded bill, and a small tube of lip balm.

If you want to make a larger version that fits a small wallet and a few more items, you can simply add to your starting chain and adjust your row count accordingly.

Abbreviations Used in This Pattern

• ch — chain
• sc — single crochet
• sl st — slip stitch
• st — stitch
• sp — space
• rep — repeat
• blo — back loop only
• RS — right side
• WS — wrong side
• pm — place marker

Pattern Notes

This bag is worked in two flat panels that are then joined together, which gives you clean, even edges and makes it easy to add a lining later if you choose. The strap is worked separately and attached at the end. The closure is optional — you can leave the bag open at the top for easy access, or add a button loop for a more secure closure.

The texture stitch used on the body of the bag is a simple back-loop-only single crochet, which creates a ribbed, ridged appearance that adds depth and visual interest without requiring any complicated technique. It looks impressive but is no harder than a standard single crochet once you get into the rhythm.

The Pattern

Step 1 — Make the Front Panel

Chain 28.

Row 1 (RS): Sc in second ch from hook and in each ch across. (27 sc) Turn.

Row 2 (WS): Ch 1, sc in blo of each st across. (27 sc) Turn.

Rows 3 through 38: Repeat Row 2.

You should now have a rectangular panel measuring approximately 6.5 inches wide by 8 inches tall. Fasten off and weave in your ends.

Step 2 — Make the Back Panel

Repeat Steps 1 through 38 exactly as written above. Fasten off and weave in your ends.

You now have two identical panels. Set them aside.

Step 3 — Join the Panels

Hold your two panels together with wrong sides facing each other. You will join them along the bottom and both side edges, leaving the top open.

Using your hook and a fresh length of yarn, join with a slip stitch to the bottom right corner. Work single crochet evenly across the bottom edge, up the left side, and across to the top left corner, working through both layers at the same time to seam them together. When you reach each corner, work two or three single crochets into the corner stitch to help it turn neatly without puckering.

Do not join the top edge — this remains open as the bag’s opening.

Once you have completed the three sides, do not fasten off yet.

Step 4 — Add the Top Edging

With your yarn still attached at the top left corner, work a single crochet edging around the entire top opening. Work one sc into each stitch or row end around the top of both panels. When you return to where you started, join with a slip stitch to the first sc.

Fasten off and weave in all ends.

Step 5 — Add the Button Loop (Optional)

If you want to add a button closure, work a short chain at the center of the back panel’s top edge. Join the chain to the edging to create a small loop, then sew a button onto the front panel in the corresponding position. A wooden button or a vintage-style button looks beautiful against cotton yarn.

For a magnetic snap closure, sew the snap pieces to the inside of the bag at the center top of each panel before you join the panels together.

Step 6 — Make the Crossbody Strap

The strap is worked as a long, narrow strip. You can make it as long or as short as you like. For a standard crossbody length that hits around the hip, you will want approximately 45 to 55 inches of finished strap. For a shorter bag that sits higher, aim for 35 to 40 inches.

Chain 8.

Row 1: Sc in second ch from hook and in each ch across. (7 sc) Turn.

Row 2: Ch 1, sc in blo of each st across. Turn.

Repeat Row 2 until your strap reaches your desired length. The back-loop-only technique gives the strap a ridged texture that matches the body of the bag beautifully.

Fasten off, leaving a long tail for sewing.

Step 7 — Attach the Strap

Thread your tapestry needle with the long tail from the strap. Align one end of the strap with the top corner of one side of the bag. Using a whipstitch or a mattress stitch, sew the strap securely to the bag. Repeat on the other side with the opposite end of the strap.

If you prefer a detachable or adjustable strap, sew D-rings to each top corner of the bag instead. Then attach your strap to the D-rings using swivel clasps. This allows you to swap straps, adjust the length, or remove the strap entirely.

Finishing Touches

Once the bag is assembled, give it a gentle blocking. Soak it briefly in cool water, squeeze out the excess moisture gently (do not wring it), and lay it flat to dry in the shape you want. Cotton yarn responds especially well to blocking and you will notice the stitches evening out beautifully as it dries.

If you are adding an interior lining, cut two pieces of your lining fabric to the dimensions of your panels plus a half-inch seam allowance on all sides. Sew them together along three sides, fold down the top edge, and slip the lining inside the bag. Tack the folded top edge of the lining to the inside of the crochet edging using a whipstitch. A cotton quilting fabric or a fun print works perfectly for this.

Customizing Your Crossbody Phone Bag

One of the greatest joys of making your own accessories is that you can customize them endlessly. Here are some ideas to make this pattern entirely your own.

Color blocking: Use two or three different colors of yarn, switching at specific rows to create bold horizontal stripes or a color-blocked look. A natural cream on the bottom with a burnt orange or cobalt blue on top is a classic summer combination.

Add a surface embellishment: Once the bag is finished, you can use embroidery thread to add small floral motifs, geometric designs, or even a simple monogram. Surface embroidery on a crochet base is easier than it looks and adds a beautiful handmade detail.

Try a different stitch pattern: If you want more visual texture, substitute the back-loop-only single crochet with a moss stitch (alternating chain spaces and single crochets) or a linen stitch. Both create a woven-looking fabric that is dense and holds its shape very well.

Play with yarn type: Jute twine gives the bag a natural, market-style feel. Nylon or paracord creates an edgy, modern look. A cotton-linen blend gives beautiful drape with added durability. Each yarn will behave differently, so always swatch first.

Add fringe or tassels: Attach a row of knotted fringe along the bottom edge, or make a single tassel to hang from one corner of the strap. Both details add movement and personality.

Skill Tips for Beginners

If you are newer to crochet, this project is a wonderful way to build your skills. Here are a few tips to help you along the way.

Keep your tension as even as possible throughout. Tension affects the size and drape of the finished bag, so try to hold your yarn with consistent pressure. If you notice your rows getting tighter or looser as you work, take a breath and adjust.

Count your stitches at the end of every row, at least for the first several rows. It is much easier to catch a missed stitch or an accidental increase early than to discover it twenty rows later.

Use stitch markers to mark the first and last stitch of each row until you get comfortable reading your work. This prevents the frustrating experience of accidentally working into the turning chain or skipping the edge stitch.

Do not be afraid to frog (rip out) and start over if something looks off. Every experienced crocheter has done it dozens of times. The yarn is reusable and the practice is always worth it.

Caring for Your Crochet Bag

Cotton yarn is machine washable in most cases, which makes it wonderfully practical for summer accessories that might get sunscreen or sand on them. Always check your specific yarn label first. Wash on a gentle cycle in cool water and lay flat to dry. Avoid putting your crochet bag in the dryer, as heat can cause cotton to shrink and lose its shape.

To help the bag keep its structure over time, give it a light blocking every once in a while. A few minutes of shaping while it is slightly damp can restore the crisp edges and even stitches to like-new condition.

Share Your Make

If you use this pattern to make your own crossbody phone bag, sharing it with the crochet community is one of the most rewarding parts of the craft. Post a photo of your finished bag in progress groups, on your favorite social platform, or in crochet community forums. Seeing how other makers interpret a pattern — the color choices, the personal touches, the creative modifications — is genuinely inspiring, and your work might be exactly the encouragement someone else needs to try their first bag project.

Tag your photos and saves so others can find this free pattern easily. The more makers who find it, the more versions of this little summer bag will exist in the world, which feels like a genuinely good thing.

Final Thoughts

A crochet crossbody phone bag is one of those projects that delivers an outsized sense of satisfaction for the time and effort you put in. It is small enough to finish in a weekend, practical enough to carry every day, and personal enough to feel like something truly yours. Whether you follow this pattern exactly or use it as a springboard for your own creative variations, the process of making it will be just as enjoyable as using it.

Summer is the perfect season to start a bag project. The evenings are long, the yarn plays beautifully in warm light, and there is no better feeling than showing up somewhere with a handmade bag slung across your shoulder that you made with your own hands. Grab your hook, pick a yarn that makes you happy, and get started. Your perfect summer bag is waiting.

Happy crocheting.
