Summertime Fishy Phone Case Free Crochet Pattern – Cool Creativities
There is something wonderfully satisfying about making your own phone case. It protects something you carry everywhere, it shows off your personal style, and when someone notices it and asks where you got it, you get to say you made it yourself. This summer, we are taking that satisfaction to a whole new level with a fun, colorful, and absolutely adorable fishy phone case that screams beach vibes, warm days, and creative energy. Whether you are a seasoned crocheter or someone who has just moved past the beginner stage and is looking for a rewarding next project, this pattern is going to become one of your favorites.
Welcome to Cool Creativities, where we believe that everyday objects deserve a handmade upgrade. Today’s free crochet pattern is all about bringing a little piece of the ocean to your fingertips — literally. This Summertime Fishy Phone Case is cute, customizable, and completely free to make with yarn you may already have sitting in your stash.
Let’s dive in.
Why a Crochet Phone Case?
Before we get into the pattern itself, let’s talk about why making your own crochet phone case is such a great idea. First, store-bought phone cases are often made from plastic or rubber, and while they do the job, they lack personality. A crocheted phone case, on the other hand, is a soft, cushioned layer that adds a unique handmade charm to your device. The yarn acts as a gentle buffer against minor bumps and scratches, and the snug fit keeps your phone secure.
Second, phone cases make wonderful gifts. If you know someone who loves the beach, ocean animals, or just adorable things in general, a little fishy phone case is the kind of thoughtful, handmade gift that people genuinely treasure. You can whip one up in just a couple of hours, make it in someone’s favorite colors, and present something that no one else in the world has.
Third — and perhaps most importantly for summer — this project is small, portable, and quick. You can bring it to the beach, work on it during a road trip, or sit with it on the porch while sipping lemonade. It is the perfect warm-weather craft.
Materials You Will Need
One of the best things about small crochet projects is that they don’t require a lot of supplies. Here is everything you need to make this Summertime Fishy Phone Case:
Yarn: You will need worsted weight yarn (size 4) in your main color for the phone case body. For this pattern, think bright and summery — turquoise, coral, sunny yellow, mint green, or ocean blue all work beautifully. You will also need small amounts of contrasting yarn for the fish appliqué. White, orange, black, and a pop of yellow are classic choices, but feel free to get creative.
Hook: A 5.0mm (US H/8) crochet hook works well with worsted weight yarn and creates a tight enough fabric to keep your phone snug without being too stiff.
Other supplies: A yarn needle for weaving in ends and sewing on embellishments, a pair of scissors, two small black buttons or safety eyes (9mm works well) for the fish eyes, and optionally a small piece of felt in a coordinating color for backing any appliqué pieces if you want extra sturdiness.
Optional: A stitch marker to keep track of rounds, especially if you are crocheting in the round.
Before you begin, measure your phone. This pattern is written as a general guideline for a standard medium-sized smartphone, roughly 6 inches tall by 3 inches wide. You may need to adjust the number of stitches or rows depending on your specific phone model. We’ll talk more about how to customize the sizing as we go.
Gauge
Gauge matters more than you might think in a phone case, because the fit needs to be just right — snug enough to hold your phone securely but not so tight that you struggle to get it in and out. With a 5.0mm hook and worsted weight yarn, you should aim for approximately 14 single crochet stitches and 16 rows to equal 4 inches. Crochet a small swatch before starting and adjust your hook size up or down as needed.
Abbreviations Used in This Pattern
ch – chain
sc – single crochet
sl st – slip stitch
st – stitch
sts – stitches
MR – magic ring
inc – increase (two single crochets in the same stitch)
dec – decrease (single crochet two together)
RS – right side
WS – wrong side
rep – repeat
Pattern Notes
This phone case is crocheted in two flat pieces that are then joined together along the sides and bottom. This makes it easy to customize the size and add embellishments to the front panel before assembly. The fish appliqué is made separately and sewn on after the main body is complete.
If you would like a ribbed texture on the case for extra grip, you can work in the back loop only (BLO) throughout the body sections. This creates a subtle horizontal texture that looks polished and adds a little stretch.
The pattern is written in US crochet terms.
The Pattern
Part One: The Case Body (Make Two)
Begin with your main color yarn.
Row 1: Ch 14. Sc in the second chain from the hook and in each chain across. (13 sts) Ch 1, turn.
Row 2–30: Sc in each stitch across. Ch 1, turn. (13 sts per row)
Continue working in this manner until your piece measures approximately 6.5 inches tall, or about half an inch taller than your phone. This extra length gives you room for a comfortable opening at the top.
At the end of your final row, do not fasten off. We will use this working yarn to join the pieces together.
Make a second identical panel and fasten off, leaving a long tail for weaving in.
Tip: If your phone is larger, add 2 stitches to your starting chain for each additional half inch of width. For taller phones, simply add more rows until the panel is the right height. Always check the fit by holding the panel against your phone before joining.
Part Two: Joining the Panels
Hold both panels together with wrong sides facing each other. The panel where you left your working yarn will be on the outside as you join. Using your working yarn and hook, work a slip stitch seam along three sides: the bottom edge and both side edges. Leave the top open.
To do this, insert your hook through the corresponding stitch on both panels at once, yarn over, and pull through all loops. Continue working slip stitches evenly along the bottom and up both sides.
When you reach the top opening, do not close it. Instead, work a single round of single crochet around the entire opening to create a neat finished edge. Slip stitch to join the round, then fasten off and weave in all ends.
Your case should now look like a little envelope, open at the top and firm along the bottom and sides. Slide your phone in to check the fit. It should feel snug but not impossibly tight.
Part Three: The Fish Appliqué
Now comes the really fun part. This sweet little fish is made in separate pieces and assembled before being sewn onto the front of the case. You can make one large fish, two medium fish, or a little school of small fish scattered across the case — it’s entirely up to you.
Fish Body:
Using your fish color yarn (orange or coral is classic, but any bright color works), make a magic ring.
Round 1: Ch 1, work 6 sc into the ring. Pull ring closed. (6 sts)
Round 2: Inc in each stitch around. (12 sts)
Round 3: Sc in next st, inc in next st rep around. (18 sts)
Round 4: Sc in next 2 sts, inc in next st rep around. (24 sts)
Round 5–7: Sc in each stitch around. (24 sts)
Round 8: Sc in next 2 sts, dec rep around. (18 sts)
Round 9: Sc in next st, dec rep around. (12 sts)
At this point, you can lightly stuff the fish body with a tiny bit of polyfill if you want a slightly dimensional look, or leave it flat for a flatter, more graphic appliqué. Fasten off, leaving a long tail for sewing.
Fish Tail:
Using your fish color or a contrasting color, ch 6.
Row 1: Sc in second ch from hook, sc in next 4 sts. (5 sts) Ch 1, turn.
Row 2: Dec, sc, dec. (3 sts) Ch 1, turn.
Row 3: Sl st across. Fasten off.
Make a second tail piece the same way. Place them together with wrong sides facing and whip stitch around the edges to create one layered tail piece. Sew the tail to the back narrow end of the fish body.
Fish Fins (Optional):
For a top fin, ch 4, sc in second ch from hook, hdc in next, dc in last. Fasten off. Sew to the top of the fish body.
For side fins, make two small triangles: ch 4, sc in second ch from hook, sc in next, sl st in last. Fasten off and sew one on each side of the body.
Assembly:
Using black buttons or safety eyes, attach the eye to the rounder front end of the fish. If you are using buttons, make sure they are sewn on very securely, especially if children will be handling the finished case.
You can also embroider a small smile using a few stitches of black yarn or thread for extra cuteness.
Sew the completed fish appliqué onto the front panel of the phone case using your yarn needle and a length of matching yarn. Take your time placing it where you like before committing — a centered fish looks sweet and simple, while an off-center fish with a bubble or two (small embroidered French knots in white) looks more playful and dynamic.
Part Four: Finishing Touches
Once your fish is sewn on and all ends are woven in, take a moment to add any final embellishments. Here are some ideas to make your case even more summery and unique:
Bubbles: Embroider small circles or French knots in white or light blue near the fish’s mouth to suggest bubbles rising to the surface.
Seaweed: Work a few chain stitches in green and tack them down in a wavy line along the bottom edge of the case.
Coral: Use a few stitches of pink or red to suggest coral along the bottom.
Stripes: Before joining the panels, try alternating stripes of two colors (like turquoise and white) for a beachy, nautical feel.
Multiple fish: Make two or three smaller fish in different colors and arrange them in a little swimming formation.
Starfish: Use the same magic ring technique to make a small five-pointed starfish in yellow or orange and add it alongside the fish.
There really is no limit to how you can personalize this case. Crochet gives you so much freedom, and part of the joy of handmade things is that every single one comes out a little differently.
Tips for Success
If this is one of your first appliqué projects, here are a few things that will help you along the way. When sewing on your fish, use a thread or yarn that closely matches the fish body color so any visible stitches blend in. Work around the entire outer edge of the fish in small, even stitches rather than just tacking it down in a few spots — this will keep the appliqué flat and prevent it from peeling up at the edges over time.
If you find that your case is stretching out after a few days of use, try working the body panels in the back loop only as mentioned earlier in the pattern notes. This creates a slightly more elastic and structured fabric that holds its shape better. You can also line the inside of the case with a piece of thin felt cut to size, which adds body and helps the case keep its form.
Washing your finished case is simple — hand wash in cool water with a small amount of gentle soap, reshape while damp, and lay flat to dry. Avoid wringing or twisting, which can distort the stitches.
