Keychain Penguin Crochet Pattern — Old Library
There is something quietly magical about a miniature penguin dangling from your keys. It is small enough to tuck into a pocket, charming enough to draw a smile from a stranger, and handmade enough to carry a little piece of you wherever you go. This pattern, which I have come to call the Old Library, draws its personality from the cozy, slightly faded warmth of old reading rooms — the kind where dust motes float in afternoon light, wooden shelves crowd every wall, and nothing moves too quickly. The penguin that emerges from this pattern has that same unhurried, dignified character. He is small, he is round, and he looks as though he has opinions about classic literature.
Whether you are a seasoned crocheter looking for a satisfying afternoon project or a confident beginner ready to try your first amigurumi-style piece, this pattern will walk you through every step. By the end, you will have a finished penguin keychain ready to attach to your bag, gift to a friend, or display in a little row on your bookshelf alongside the other characters you will inevitably want to make once you finish this one.
What Makes This Pattern Special
The Old Library penguin keychain is worked almost entirely in the round, using tight single crochet stitches to create a firm, dense fabric that holds its shape well without needing extra stuffing to stay plump. The body is constructed as one main piece with a separate belly panel stitched on afterward, which gives the penguin its characteristic tuxedo look without any complicated colorwork. The wings are simple flat ovals, the feet are tiny and satisfying to make, and the face comes together with just a few carefully placed embroidery stitches and safety eyes.
The finished penguin measures approximately 2.5 to 3 inches tall, which makes it a perfect keychain size — noticeable enough to find easily in a bag but small enough not to weigh down your keys. The key ring is attached through the top of the head using a small loop worked into the pattern, so it sits naturally upright when hanging.
Materials You Will Need
Before you sit down to crochet, gather everything you need so the process stays smooth and uninterrupted. Here is what this pattern calls for.
For yarn, you will need a small amount of black worsted weight yarn for the body, a small amount of white or cream worsted weight yarn for the belly panel, and a very small amount of orange or golden yellow yarn for the beak and feet. The exact yardage is minimal — this project is a perfect way to use scraps from larger projects. If you have leftover yarn from any black or navy sweater project, it will work beautifully here.
You will need a 3.5mm crochet hook, which is slightly smaller than what most worsted weight patterns call for. The tighter gauge is intentional. Working with a smaller hook creates a denser fabric that hides the stuffing inside and gives the penguin a firmer, more polished look.
Other supplies include a small amount of polyester fiberfill stuffing, two 6mm or 8mm black safety eyes, a yarn needle for sewing pieces together and weaving in ends, scissors, stitch markers to keep track of your rounds, and a small key ring or split ring to attach at the end. Optionally, a small piece of cardboard or plastic canvas cut to fit inside the base of the body can help the penguin sit flat if you ever want to display him standing upright rather than hanging.
Abbreviations and Stitches Used
This pattern is written using standard American crochet terminology.
MR stands for magic ring, which is how you will begin most of the circular pieces. If you are not comfortable with the magic ring, you can chain 2 and work the required number of stitches into the second chain from the hook instead.
SC means single crochet. Inc means increase, which is two single crochet stitches worked into the same stitch. Dec means invisible decrease, worked by inserting the hook through the front loops of the next two stitches and pulling through both, then completing the stitch as normal. Sl st means slip stitch. Ch means chain. FO means fasten off.
The pattern is worked in continuous rounds unless otherwise stated. Use a stitch marker to mark the first stitch of each round and move it up as you go. This keeps your stitch count accurate and your rounds aligned.
Pattern Instructions
The Body
Begin with your black yarn and make a magic ring.
Round 1: Work 6 SC into the magic ring. Pull the ring closed. You will have 6 stitches.
Round 2: Inc in each stitch around. You will have 12 stitches.
Round 3: Work SC 1, Inc, repeat around. You will have 18 stitches.
Round 4: Work SC 2, Inc, repeat around. You will have 24 stitches.
Round 5: Work SC 3, Inc, repeat around. You will have 30 stitches.
Rounds 6 through 10: Work one SC in each stitch around, no increases or decreases. You will have 30 stitches in each round.
At the end of round 10, you are at the widest point of the body. This is the moment to insert your safety eyes. Place them between rounds 7 and 8, spacing them approximately 6 stitches apart. The exact placement affects the personality of the penguin significantly, so take a moment before securing them. Closer together gives him a more focused, scholarly expression. A little further apart gives him a wider, more surprised look. Once you are happy with the placement, press the backs firmly onto the posts to lock them in.
Round 11: Work SC 3, Dec, repeat around. You will have 24 stitches.
Round 12: Work SC 2, Dec, repeat around. You will have 18 stitches.
Begin stuffing the body now. Add a small, firm amount of fiberfill and continue adding as you close the remaining rounds. The stuffing should be firm but not so tight that it stretches the stitches and shows the white fiberfill through the black yarn.
Round 13: Work SC 1, Dec, repeat around. You will have 12 stitches.
Round 14: Work Dec around. You will have 6 stitches.
Work a slip stitch into the next stitch and fasten off, leaving a tail long enough to sew the gap closed if needed. Use your yarn needle to close the remaining hole neatly, then weave in the end.
The Head Loop
Before you move on to the other pieces, this is the best time to create the loop at the top of the head for the key ring. Thread a 12-inch length of black yarn onto your yarn needle. Identify the top center of the head — this is roughly where the original magic ring sits. Insert your needle down through the center, pull it back up about 2 stitches away, and then repeat this two or three times to create a reinforced anchor point. Form a small loop approximately half an inch long and secure it by wrapping the yarn around the base of the loop several times before weaving in the ends tightly. This loop needs to hold the weight of your keys, so take the time to make it secure. Alternatively, you can crochet a small chain of 4 to 5 stitches, slip stitch into the first chain to form a loop, and attach it to the top of the head with your yarn needle.
The Belly Panel
Switch to your white or cream yarn for this piece. The belly panel is worked flat in rows to create an oval shape.
Chain 4.
Row 1: SC into the second chain from the hook and into each chain across. Turn. You will have 3 stitches.
Row 2: Ch 1, Inc into the first stitch, SC into the middle stitch, Inc into the last stitch. Turn. You will have 5 stitches.
Rows 3 through 5: Ch 1, SC in each stitch across. Turn. You will have 5 stitches in each row.
Row 6: Ch 1, Dec over the first two stitches, SC in the middle stitch, Dec over the last two stitches. Turn. You will have 3 stitches.
Row 7: Ch 1, SC in each stitch across. Fasten off, leaving a long tail for sewing.
Position the belly panel on the front of the body, centering it between the eyes and extending down toward the base. Pin it in place if helpful, then use the yarn tail to whipstitch around the entire perimeter of the panel, attaching it securely to the body. The white oval should sit neatly centered on the front. Weave in all ends.
The Wings (Make Two)
Return to your black yarn for the wings. Each wing is a small flat oval.
Make a magic ring.
Round 1: Work 6 SC into the ring. Pull closed.
Round 2: Inc in each stitch. You will have 12 stitches.
Round 3: Work SC 1, Inc, repeat around. You will have 18 stitches.
Work one round of slip stitches around the entire edge of the oval. This gives the wing a neat, flattened border that makes sewing easier and gives the finished wing a more defined shape.
Fasten off, leaving a long tail. Do not stuff the wings. Position them on either side of the body, approximately at the midpoint height, angling them very slightly downward and forward for a natural pose. Sew them on securely using the yarn tail, stitching through both the wing and the body several times before weaving in the end.
The Beak
Switch to your orange or yellow yarn. The beak is a tiny triangle worked flat.
Chain 3.
Row 1: SC into the second chain from the hook, SC into the next chain. Turn. You will have 2 stitches.
Row 2: Ch 1, Dec over both stitches. Turn. You will have 1 stitch.
Fasten off, leaving a long tail. Fold the piece very slightly to give it a small three-dimensional point, then sew it onto the face centered between and just below the eyes. The beak should sit at approximately the same level as the lower edge of the eyes. Stitch it down firmly so it stays perky.
The Feet (Make Two)
Using your orange or yellow yarn, make a magic ring.
Round 1: Work 4 SC into the ring. Pull closed.
Round 2: Inc in each stitch. You will have 8 stitches.
Round 3: SC in each stitch. You will have 8 stitches.
Slip stitch to join and fasten off, leaving a long tail. The feet are small flat discs. Flatten them slightly with your fingers and sew them onto the base of the body, angling outward in a slight V-shape so the penguin looks as though he is standing in that characteristic wide-footed penguin stance.
Finishing Touches
With all pieces attached, take a moment to look at your penguin from every angle. Adjust anything that feels off — a wing that sits too high, a foot that angles awkwardly, a beak that needs a gentle repositioning before the yarn is fully woven in. This is the stage where small adjustments make a meaningful difference in the finished character of the piece.
If you want to add extra personality, you can embroider tiny details with a single strand of yarn or embroidery floss. A few straight stitches below each eye suggest the faint impression of cheeks. A tiny straight stitch above each eye can suggest a faint brow that gives him a more thoughtful expression — fitting for an Old Library penguin.
Thread your key ring or split ring through the loop at the top of the head. Give it a gentle tug to confirm it is secure. If you feel any give in the loop, reinforce it before putting the keychain into regular use.
Tips for Getting the Best Results
Gauge matters more in amigurumi-style projects than in many other types of crochet. If your stitches are too loose, the stuffing will show through and the shape will feel soft and floppy rather than firm and sculptural. Work tightly and consistently throughout, and do not hesitate to go down a hook size if your fabric still feels open.
When closing the final rounds of the body, work slowly and check your stitch count at the end of each decrease round. A small error in one round compounds over the next, and catching it early saves the frustration of having to unravel several rounds.
The magic ring is worth learning if you have not used it before. It gives a seamless, professional beginning to any worked-in-the-round piece and eliminates the small hole that can form when starting from a chain. There are many clear tutorials available, and the technique becomes second nature after just a few tries.
Ideas for Variation
Once you have made your first Old Library penguin, you will naturally start imagining variations. The basic construction lends itself well to personalization. A tiny scarf knitted in seed stitch from a length of contrasting yarn and wrapped around the neck transforms the penguin into a winter version. A miniature top hat, cut from a small scrap of black felt and glued in place, gives him a formal air. A tiny book made from folded white paper and a scrap of fabric for the cover, tucked under one wing, fully commits to the Old Library theme.
Color variations are equally rewarding. While the black and white tuxedo coloring is the classic choice, a navy body with a pale blue belly gives the penguin a softer, more wintry appearance. A dark charcoal body with a silvery belly reads as more sophisticated and modern. Experimenting with different shades of orange and yellow for the beak and feet yields subtly different personalities across what is essentially the same pattern.
A Note on Gifting
Handmade keychains make genuinely thoughtful gifts because they are small enough to feel personal and practical enough to be used daily. If you are making this penguin as a gift, consider pairing it with a small handwritten note explaining that it is crocheted by hand — many people do not realize that small amigurumi pieces require as much care and skill as larger projects, and a brief acknowledgment of the craft adds meaning to the gift.
For children who love penguins, the keychain can double as a bag charm or a small toy. If you are making it for a young child, you may want to omit the safety eyes and embroider the eyes instead using black yarn, eliminating any choking hazard. Embroidered eyes have a slightly softer, more vintage appearance that suits the Old Library character particularly well.
Storing and Caring for Your Keychain
Acrylic worsted weight yarn, which is the most commonly used fiber for amigurumi-style pieces, is remarkably durable and easy to care for. If your keychain gets dusty or grimy from daily use — which it will, eventually — you can hand wash it gently in cool water with a small drop of mild dish soap, rinse thoroughly, and press out the excess water in a clean towel before leaving it to air dry. Avoid wringing or twisting the piece, as this can distort the shape of the stuffed body.
If you use a natural fiber like cotton or wool, the care instructions change slightly. Cotton is quite washable but slow to dry. Wool needs careful cool water handling to avoid felting, which would permanently alter the texture and size of the piece. For a keychain that will see daily use and occasional washing, acrylic is a practical and sensible choice.
The Old Library penguin keychain is one of those patterns that rewards you far beyond the time it takes to make. An afternoon’s worth of crochet produces something that will last for years, accompany you daily, and prompt small conversations with curious strangers who notice the little tuxedoed bird dangling from your bag. He is dignified. He is round. He belongs in a library, and now he belongs to you.
