Why You’ll Love This Crochet Beer Mug Keychain

Keychains are one of those perfect crochet projects that never go out of style. They’re small enough to finish in a single sitting, use up yarn scraps, and make incredibly thoughtful handmade gifts. This little beer mug pattern takes all of that and adds a playful, fun element that makes it stand out from the usual amigurumi keychain designs.

The finished mug is worked in the round, stuffed lightly so it holds its shape, and topped with a fluffy white “foam” detail that makes it instantly recognizable as a frothy pint. You can make a whole set of them — one for every member of your crochet group, your family, or your favorite coworkers — and no two need to look exactly alike.

Beyond gifts, these also make great bag charms, zipper pulls, backpack accessories, or even ornaments if you swap out the keychain ring for a small loop of ribbon. The possibilities are wonderfully flexible.

Materials You’ll Need

One of the best things about this project is that it requires very little in the way of supplies. You likely have most of what you need already sitting in your yarn stash.

Yarn: You’ll need a small amount of worsted weight yarn in golden yellow or amber for the mug body, and a small amount of white or cream for the foam. Exact yardage is minimal — think leftover scraps from other projects. Acrylic yarn works beautifully here because it’s washable and holds its shape well, though cotton yarn is a great alternative if you prefer a slightly firmer texture.

Hook: A 3.5mm or 4.0mm crochet hook works well with worsted weight yarn for this project. You want your stitches to be tight enough that the stuffing doesn’t peek through, so go down a hook size from what the yarn label recommends if needed.

Stuffing: A small amount of polyfill stuffing to give the mug its shape. You won’t need much — just enough to fill the body and keep it from going flat.

Notions: A yarn needle for weaving in ends and sewing pieces together, scissors, a stitch marker or a small piece of contrasting yarn to mark the beginning of your rounds, a split ring keychain or lobster clasp keychain ring, and a small length of chain or jump ring to attach your finished mug.

Optional: Brown or tan yarn to add a subtle shading detail to the mug body, or a tiny piece of felt in white to create a stylized foam look if you prefer not to crochet the foam separately.

Abbreviations Used in This Pattern

This pattern uses US crochet terminology. Here’s a quick reference for all the stitches you’ll encounter.

MR — Magic ring (also called magic circle)
ch — Chain
sl st — Slip stitch
sc — Single crochet
inc — Increase (two single crochets in the same stitch)
dec — Invisible decrease (also called invdec; insert hook through front loops of next two stitches, yarn over, pull through both loops, yarn over, pull through remaining two loops)
BLO — Back loop only
FLO — Front loop only
st(s) — Stitch(es)
rnd — Round
rep — Repeat

Finished Size

The finished keychain measures approximately 1.5 inches wide and 1.75 inches tall, not counting the handle or keychain hardware. This makes it a comfortable, chunky little accessory that’s easy to spot in your bag without being cumbersome.

If you want a larger version — say, a bag charm rather than a true keychain — simply go up in yarn weight and hook size. A bulky yarn with a 6mm hook will give you a piece roughly twice the size, and it still works up quickly and charmingly.

Pattern Instructions

Part One: The Mug Body

The mug body is worked from the bottom up in continuous rounds. Use yellow or amber yarn and your chosen hook size.

Round 1: Start with a magic ring. Work 6 sc into the ring. Pull the ring closed. (6 sts)

Round 2: Inc in each stitch around. (12 sts)

Round 3: Sc 1, inc repeat around. (18 sts)

Round 4: Sc 2, inc repeat around. (24 sts)

Round 5: Work in BLO — sc in each stitch around. This creates a subtle ridge that defines the bottom edge of the mug nicely and gives it a slightly structured base. (24 sts)

Rounds 6 through 12: Sc in each stitch around for seven rounds. (24 sts per round)

These rounds form the main body of the mug. As you work, you’ll see the cylindrical shape taking form.

Round 13: Working in FLO — sc in each stitch around. This ridge will serve as the top edge where the foam detail attaches. (24 sts)

Round 14: Sc in each stitch around. (24 sts)

At this point, before you continue, stuff your mug body firmly with polyfill. You want it to feel solid and hold a nice cylindrical shape, but don’t overstuff it to the point where it looks distorted.

Round 15: Sc 2, dec repeat around. (18 sts)

Round 16: Sc 1, dec repeat around. (12 sts)

Round 17: Dec around. (6 sts)

Fasten off, leaving a tail long enough to close the top. Use your yarn needle to weave through the front loops of the remaining six stitches and pull tight to close. Weave in that end securely on the inside of the mug.

Part Two: The Foam Top

The foam is what transforms this little crochet cylinder into an unmistakable beer mug. Use white or cream yarn for this section.

Round 1: Start with a magic ring. Work 6 sc into the ring. Pull the ring closed. (6 sts)

Round 2: Inc in each stitch around. (12 sts)

Round 3: Sc 1, inc repeat around. (18 sts)

Round 4: Sc 2, inc repeat around. (24 sts)

Now you’ll create the bumpy, bubbly foam texture. This is done with a simple modified round using slip stitches and chain stitches.

Round 5 (Foam Texture Round): Sl st in next st, ch 2, sl st in same st — repeat this sequence around all 24 stitches. This creates a series of small bobble-like loops that beautifully mimic the frothy top of a pint of beer.

Fasten off and leave a long tail for sewing.

Part Three: The Handle

The handle is a simple flat piece that you’ll sew onto the side of the mug. It can be made in the same yellow or amber color as the mug body.

Chain 10.

Row 1: Starting in the second chain from the hook, sc across. (9 sts)

Row 2: Ch 1, turn. Sc across. (9 sts)

Row 3: Ch 1, turn. Sc across. (9 sts)

Fasten off, leaving a generous tail for sewing. This creates a small, slightly thick rectangular strip that curves nicely when attached to the mug.

Assembling Your Crochet Beer Mug Keychain

Now comes the satisfying part — putting it all together.

Attaching the Foam: Hold the foam piece over the top opening of the mug body, aligning the edges. The foam circle should be about the same diameter as the mug opening, which is exactly what you made. Using your yarn needle and the tail from the foam piece, sew the foam down all the way around the edge, working through both the foam and the top round of the mug body. Pull your stitches firmly so the foam sits flush against the top and doesn’t flop around. Weave in the end when you’re finished.

Attaching the Handle: Fold the rectangular strip you made for the handle and curve it slightly in your fingers to get a sense of how it will look when attached. Position it on one side of the mug body, aligning the short ends of the strip against the mug at the top and bottom. Using your yarn needle, sew each end of the handle securely to the mug. Take several passes with your needle to make sure it won’t pull loose with regular use. Weave in all ends.

Adding the Keychain Hardware: Before you close everything up completely — or at this finishing stage — you’ll need to attach your keychain ring. The easiest method is to use a small jump ring or a piece of chain. Fold a short length of chain in half, pass it through a jump ring, then pass the jump ring through the top loop or seam of the mug near where the handle attaches. Close the jump ring securely. Attach your keychain ring or lobster clasp to the other end of the chain. Alternatively, you can crochet a small loop of chain stitches at the very start of your project and work it into the seam at the top of the mug.

Tips for the Best Results

A few small details can make a big difference when it comes to this tiny project.

Tension matters more than usual. Because this mug is so small, any looseness in your stitches will be immediately visible. Try to keep your tension consistent and slightly tighter than you normally would. If you find that the stuffing is showing through the stitches, simply go down a hook size.

The invisible decrease is your friend. Using the standard decrease (inserting through both loops) can leave a visible bump on the outside of your work. The invisible decrease, worked through the front loops only of two adjacent stitches, creates a much smoother, more professional finish on the outside of the mug.

Stuff as you go. It’s easier to add a little stuffing as you decrease down the top of the mug rather than trying to cram it all in at once at the end. This also helps you gauge how firmly packed you want the finished piece.

Use a stitch marker. In continuous rounds, it’s easy to lose track of where one round ends and the next begins. A stitch marker (or a simple safety pin, or even a small piece of contrasting yarn) placed at the first stitch of each round will keep you on track and prevent you from accidentally gaining or losing stitches.

Block the foam piece. If your foam piece seems to curl a bit, a light blocking with a damp cloth and a warm iron can coax it flat. This makes sewing it onto the mug much easier.

Customization Ideas

Once you’ve made your first crochet beer mug keychain, you’ll likely find yourself wanting to experiment. Here are some ideas to spark your creativity.

Color variations: While golden yellow is the classic beer color, there’s no rule that says you have to stick to it. Dark brown gives you a stout or porter. Red-amber creates a beautiful ale. Very pale yellow mimics a light lager. You can even go completely non-literal and make your mug in bright pink or teal for a purely decorative charm.

Dark foam: Some beers, like Guinness, are famous for their creamy white foam on top of a very dark body. Making your mug body in deep brown and your foam in off-white or cream creates a wonderfully realistic-looking stout mug.

Embroidery details: Use a contrasting color of yarn or embroidery floss to add a little label to the front of your mug. A tiny letter or a simple X or heart stitched onto the body adds a personalized touch that makes these keychains ideal as custom gifts.

Mini pretzel companion: If you want to create a little set, a tiny crocheted pretzel or a small crocheted peanut worked in the same scale makes a delightful companion piece to attach alongside the mug.

Different hardware: Instead of a keychain ring, attach a magnetic clasp to make a bag charm that stays in place. Or, as mentioned earlier, a loop of ribbon turns this into a festive ornament perfect for a bar-themed Christmas tree.

Perfect Gift Ideas Using This Pattern

Because this pattern works up so quickly — most crocheters finish one mug in about an hour or less once they’ve practiced the steps a couple of times — it lends itself perfectly to batch crafting for gifts.

For a birthday gift to a beer-loving friend, make a set of four or six in different beer colors and present them in a small gift box tied with twine. For a bachelorette party or bachelor party, make a personalized mug keychain for each guest as a party favor. For the holiday season, a handmade crochet beer mug keychain attached to a gift tag or tucked into a stocking feels both thoughtful and festive.

Teachers, coworkers, neighbors, and family members are all great recipients. Because the materials cost almost nothing when you’re using yarn scraps, these make incredibly budget-friendly handmade gifts that still feel special and personal.

Skill Level and Learning Opportunities

This pattern is designed to be accessible to beginners who have already learned the basics of working in the round, but it also offers a few interesting techniques that will push you slightly beyond the absolute fundamentals. If you’ve never tried the invisible decrease before, this is a fantastic project to practice it on — the mug is small enough that the learning curve feels low-stakes, but the results are visible enough to be satisfying.

The foam texture round is also a nice introduction to combining slip stitches with chain stitches to create texture, which is a technique that pops up in lots of other crochet patterns. Mastering it on a tiny piece like this will make you feel confident tackling it in larger projects later.

If you’re sharing this pattern with a beginner in your life, encourage them to make two or three mugs back-to-back. The repetition is wonderful for building muscle memory, and by the third mug they’ll likely find themselves working much more quickly and confidently than they did on the first.

Storing and Caring for Your Finished Keychain

Since this keychain lives in bags, pockets, and on belt loops, it’s going to get handled quite a bit. A few care tips will help it stay looking its best.

If you used acrylic yarn, the mug is machine washable on a gentle cycle and can be air dried. Place it in a small mesh laundry bag to protect the hardware during washing. Cotton yarn is also fully washable. If you used a wool or wool-blend yarn, spot-clean only to prevent felting.

Over time, the stuffing may compress slightly with regular use, but this is easy to address. Simply open a small seam on the underside, add a tiny bit of fresh polyfill, and sew it back up.
