Free Crochet Coin Purse Keychain Pattern: The Cutest Way to Organize Your Coins

If you’ve ever dug through the bottom of your bag searching for exact change, you already know the struggle. Coins have a way of disappearing into the depths of purses, pockets, and tote bags, turning a simple transaction into a treasure hunt. The solution? A tiny, charming crochet coin purse keychain that clips right onto your bag, your keys, or a belt loop so your coins are always right where you need them.

This free crochet coin purse keychain pattern is beginner-friendly, works up in under an hour, and makes the most satisfying little project when you want something quick and practical. It’s also one of those patterns that becomes slightly addictive — because once you’ve made one, you’ll want to make a dozen in every color you own. They’re perfect for gifting, selling at craft fairs, or simply treating yourself to a little handmade accessory that actually solves a real everyday problem.

Let’s dive in.

Why Crochet a Coin Purse Keychain?

Before we get into the pattern, let’s talk about why this little project is so worth your time.

First, it’s genuinely useful. A coin purse keychain keeps your loose change contained and accessible without requiring you to dig through your entire bag. Attach it to the outside of your purse and you can grab coins with one hand at the checkout counter. Clip it to your gym bag and you’ll always have quarters for a locker. Keep it on your keyring and you’ll never be short for a parking meter again.

Second, it’s a fantastic stash buster. This project uses a surprisingly small amount of yarn — we’re talking leftovers from other projects. Those little balls of yarn you’ve saved because they were too pretty to throw away? This is their moment.

Third, this is one of the best patterns for practicing foundational crochet skills. You’ll work in the round, create a flat base, add some structure with a stitch pattern, and finish with a zipper or snap closure. Every technique you practice here translates directly to bigger projects down the line.

And finally, these coin purse keychains make wonderful handmade gifts. Tuck a few coins inside, add a little tag, and you have a thoughtful, practical present that people will actually use.

Materials You’ll Need

One of the best things about this pattern is how minimal the supply list is. Here’s what you’ll want to gather before you start.

Yarn: About 50 to 75 yards of worsted weight yarn (size 4) works beautifully for this project. You can also use cotton yarn, which gives a slightly stiffer fabric that holds its shape really well — ideal for a purse. Bulky yarn can work too but will produce a larger finished object. If you want to experiment with size, thinner yarn with a smaller hook gives a more refined, delicate look.

Crochet Hook: A 5mm (H/8) hook is ideal for worsted weight yarn. If you’re using cotton, you might prefer a 4.5mm hook to get a tighter stitch. As always, gauge matters less here than achieving a fabric you’re happy with — dense enough to hold its shape but not so stiff it’s uncomfortable to work with.

Zipper: A 4-inch or 5-inch zipper works perfectly for this pattern. You can find these at any craft store or order them in bulk online. Pick a color that complements your yarn or go for a fun contrast — a bright yellow zipper on navy yarn looks incredibly chic.

Keychain Ring or Lobster Clasp: You’ll need a small metal ring or lobster clasp to attach the finished purse to your keys or bag. These usually come in multi-packs at craft stores and are inexpensive.

Yarn Needle: For weaving in ends and, if you prefer, for sewing in the zipper.

Sewing Needle and Thread: Optional, but makes attaching the zipper a bit easier and more secure than yarn alone.

Scissors: Always essential.

Stitch Markers: Optional but helpful for marking the beginning of each round.

Gauge and Finished Size

Working in single crochet with worsted weight yarn and a 5mm hook, your gauge should be approximately 14 stitches by 16 rows in a 4-inch square. That said, because this is a small project, gauge isn’t critical as long as your fabric is nice and dense. A loose, drapey fabric won’t hold coins well, so err on the side of tighter tension.

The finished coin purse measures approximately 3.5 inches wide by 3 inches tall — just the right size for a handful of coins without being bulky.

Pattern Notes

This purse is worked in continuous rounds from the bottom up. You’ll create a flat oval base first, then work up the sides, and finally finish the opening edge so it’s ready for your zipper.

If you prefer to work in joined rounds, simply slip stitch to the first stitch of each round and chain 1 before beginning the next. The finished result will be essentially the same.

The base is an oval worked like a traditional flat-bottom bag base — you’ll begin with a foundation chain, work single crochets along one side, increase around the end, work back along the other side, and increase around the other end. This gives you a nice rounded rectangular shape that sits neatly when stuffed with coins.

The Pattern

Foundation: Oval Base

Begin with a foundation chain of 8.

Round 1: Starting in the second chain from the hook, sc 6 across. In the last chain, work 3 sc (this creates the curve at the end). Now rotate your work and sc along the bottom of the foundation chain — you’ll pick up 5 stitches. In the very first chain you started with, work 2 sc to complete the curve at this end. You should have 16 stitches total. Do not join; place a stitch marker at the beginning of the round.

Round 2: Inc, sc 5, inc 3 times, sc 5, inc twice. (24 sts)

Round 3: Sc 1, inc, sc 5, (sc 1, inc) 3 times, sc 5, sc 1, inc, sc 1. (30 sts)

Round 4: Sc 2, inc, sc 5, (sc 2, inc) 3 times, sc 5, sc 2, inc. (36 sts)

You now have a nice, flat oval that forms the base of your coin purse. If you want a slightly larger purse, you can add one more increase round following the same pattern, adding 6 stitches each time.

Building the Sides

Now you’ll start working straight up to create the walls of the purse.

Round 5: Working in BLO, sc around all 36 stitches. (36 sts)

Working in the back loop only for this one round creates a neat fold line between the base and the sides — a little trick that gives your purse a crisp, defined bottom edge and helps it sit flat.

Rounds 6–14: Sc around in both loops as normal. (36 sts each round)

Continue working straight rounds of single crochet until the sides measure about 2.5 to 3 inches tall. Depending on your tension and yarn, this usually falls around round 14 or so. You want the purse to be deep enough to hold coins securely without them spilling out when the zipper is open.

At this point, you have a couple of options for adding texture and visual interest to the body of the purse. You can swap to half double crochet for the main body rounds, which creates a slightly taller, softer-looking stitch. Alternatively, try working a simple ribbed texture by alternating front post and back post single crochets, which adds a stretchy, tactile quality to the fabric. For a beginner, plain single crochets are perfectly lovely and let the yarn color shine.

Creating the Top Opening Edge

Round 15: Sc around. (36 sts)

Round 16: Sl st loosely around all stitches. (36 sts)

The slip stitch round at the top creates a neat, tidy edge that will sit flat against the zipper tape when you attach it. Keep your slip stitches loose so the opening doesn’t pull or pucker.

Fasten off and weave in your ends.

Adding the Keychain Loop

Before attaching the zipper, decide where you want the keychain loop. Most people prefer it at one of the top corners, slightly off-center, so it hangs nicely.

Cut a piece of yarn about 12 inches long. Fold it in half and use the folded end to pull through the top edge of the purse at your chosen spot, creating a small loop. Thread both tails through the loop and pull snug to create a lark’s head knot. Braid or twist the two tails together for about an inch, then tie off and trim the ends. Thread your keychain ring or lobster clasp through this loop.

Alternatively, you can purchase a small piece of ribbon or webbing and loop it through a metal D-ring for a more polished look.

Attaching the Zipper

This is the step that intimidates most crocheters, but it’s truly much easier than it looks. Take your time, and you’ll get a clean, professional result.

Lay your zipper face down along the inside of the top opening of the purse. Align the zipper tape with the slip stitch edge so the zipper pull will be on the outside of the purse when everything is assembled. Pin it in place if that helps.

Using a sewing needle and thread (or a yarn needle and a length of yarn in a matching color), whipstitch the zipper tape to the inside of the purse opening, working through the slip stitch edge. Go slowly, keeping your stitches even, and check regularly that the zipper is sitting straight and the purse isn’t puckering.

Sew both sides of the zipper in place, then open and close it a few times to make sure it moves freely and the purse opens and closes as expected. Knot and hide your thread ends inside the purse.

If you’ve never attached a zipper to a crochet project before, it can help to watch a short video tutorial to see the hand motions — but once you’ve done it once, it becomes second nature.

Variations and Customization Ideas

Once you have the basic pattern down, there are so many ways to make it your own.

Color blocking is an easy and stunning effect — simply change yarn colors every few rounds as you work up the sides. Alternating two colors gives a classic stripe effect, while a gradual fade using a gradient or ombre colorway creates something that looks almost painterly.

Adding a lining takes a bit more effort but gives a beautifully finished interior that protects against yarn stretch and makes the purse feel more luxurious. Cut a piece of cotton fabric slightly smaller than the inner dimensions of the purse, fold the edges under, and hand-stitch it in place before attaching the zipper.

Embellishments like crocheted flowers, small buttons, embroidered initials, or even appliquéd shapes can transform a simple coin purse into a real statement piece. A small crochet cactus or mushroom stitched to the front takes about ten extra minutes and makes the whole thing instantly adorable.

Changing the closure is another fun option. If you prefer a snap closure or a magnetic clasp over a zipper, you can finish the top edge with a simple single crochet border and attach your chosen hardware. Some people even use a button and loop closure for a vintage look.

Sizing up the pattern is easy — just add more increase rounds to the oval base and work more rounds on the sides. A coin purse made with this method at double the size becomes a perfectly charming small makeup bag or card holder.

Tips for the Best Results

A few notes that can make a real difference in how your finished purse looks and functions.

Use a stitch marker consistently. Working in continuous rounds is easy to lose track of, and there’s nothing more frustrating than realizing halfway up the sides that you’ve gained or lost several stitches. A simple piece of contrasting yarn works as a stitch marker in a pinch.

Block your finished purse before attaching the zipper. A quick wet block or a light steam with an iron (if your fiber content allows) helps the fabric relax, evens out any tension inconsistencies, and gives you a much neater finished piece.

Take your time with the zipper. Rushing this step is the most common source of frustration. Work slowly, pin carefully, and check your alignment frequently. It makes all the difference.

If your oval base comes out slightly wonky, don’t stress — it will even out as you work up the sides, and once the purse is stuffed with coins it will hold its shape.

Frequently Asked Questions

Can I use a different yarn weight? Absolutely. Thinner yarn produces a more delicate, refined purse. Thicker yarn creates something chunkier and more casual. Just adjust your hook size accordingly and keep in mind that your yardage needs will change.

How long does this take to make? For an experienced crocheter, this works up in 45 minutes to an hour. If you’re newer to crochet, allow two to three hours, especially if it’s your first time attaching a zipper.

Can I sell items made from this pattern? Yes! This is a free pattern shared for personal and small-scale commercial use. If you sell items made from this pattern, a credit and a link back to the pattern is always appreciated.

What if I don’t want a keychain ring — can it just be a regular coin purse? Of course. Simply skip the keychain loop step and you’ll have a sweet little standalone coin purse.

My sides are curling inward — what should I do? Try working with a slightly larger hook, or loosen your tension a bit. A hook half a size up can completely change the drape and structure of the fabric.

Finishing Up

Once your zipper is in and your keychain ring is attached, give your new coin purse a final look over, trim any remaining yarn ends, and you’re done. Test the zipper a few times, load it up with some coins, clip it to your bag, and appreciate the satisfaction of having made something genuinely useful with your own hands.

This free crochet coin purse keychain pattern is one of those small projects that punches well above its weight in terms of satisfaction. It’s quick, it’s practical, it uses minimal materials, and the finished result is something you’ll actually reach for every day.

Whether you’re new to crochet and looking for a confidence-building project, a seasoned maker searching for the perfect last-minute gift, or somewhere in between, this pattern has everything you need. Keep it bookmarked, share it with a friend, and most importantly — enjoy the process.

Happy crocheting!
