Mini Whale Keychain Crochet Pattern — Free Step-by-Step Tutorial

This mini whale takes about 1–2 hours to crochet, uses roughly 20g of chenille yarn, and the best part: you don't sew a single piece. The tail and fins are built directly onto the body in Round 10, so when you fasten off, you're done — no yarn needle assembly required.

I designed this pattern around Sweet Ultra-Fine 2mm Chenille Yarn because the ultra-fine weight gives you a tight enough stitch to hold stuffing in, while still feeling impossibly soft. Cotton yarn works too, but the chenille gives it that plush toy texture that makes people pick it up and not want to put it down.

What You'll Need

If you don't have chenille yarn on hand, any sport-weight yarn with a 2.5mm hook will work. But I'll be honest — chenille is what makes this whale look like something you'd buy in a shop rather than something you made on your couch. The Sweet 2mm comes in 50+ colours, so you're not limited to classic blue. I've tested dusty pink, lavender, and mint green — they all look great.

The Pattern: Body

Work in continuous rounds. Do not join or turn unless instructed. Use a stitch marker to track the first stitch — chenille yarn makes it hard to see where your rounds begin, so don't skip this.

Start with Light Blue (#18).

Rounds 1–5 build the increasing disc that forms the whale's head. Rounds 6–9 are straight — no increases, no decreases. These four even rounds create the main body shape. Move your stitch marker up each round so you don't lose your place.

Round 10 — Tail & Fins (The Fun Part)

This is the trickiest round in the whole pattern, but it's also what makes it special — the tail and side fins are crocheted directly onto the body. No separate pieces, no sewing.

Tail (worked first):

From sl st position, ch 5, skip 2 ch from hook, 4 sc back along chain. That's the first tail fluke. Ch 5 again, skip 2 ch from hook, 4 sc back along chain. That's the second fluke.

Continue around the body:

Starting at the 1st st, sc 6.

First side fin:

On the outer half of the round: sl st, ch 2, dc in same st, dc in next st, ch 2, sl st in same st. This creates a small fan-shaped fin that sits flat against the body.

Continue:

Sc to st 23.

Second side fin:

In st 24: sl st, ch 2, dc in same st, dc in next st, ch 2, sl st in same st. Then sc 6. (30 sts)

Take your time with this round. If you're following along with the video tutorial, the chapter at 13:55 walks through every stitch.

Colour Change & Decreasing

Change to Cream White (#02) on the last pull-through of Round 10. This is important — switch on the last yarn-over, not the first stitch of the new colour, or you'll get a visible jog.

Before Round 12: Insert the 6mm safety eyes between Rounds 8 and 9, about 6–8 stitches apart. Push the post through from the outside, then click the backing on the inside. Take an extra 30 seconds to check they're level — it matters more than you'd think on something this small.

Before closing: Stuff the body firmly with polyester fiberfill. You want a round shape, but not so tight that the stitches gap and you see stuffing through the chenille. Push filling into the head area evenly.

Finishing

Leave a long tail. Thread your yarn needle and weave through the front/outer loops of the remaining 12 stitches counterclockwise, then pull tight to close the opening. Weave in all ends.

That's it. No assembly, no sewing fins on, no loose pieces. The whale is done.

Keychain loop (optional): Before you close the final round, chain 10–12 stitches at the top of the head, attach a small keychain clasp, and slip stitch back into the body to secure. This turns your whale into a bag charm that actually holds up to daily use.

Colour Variations to Try

The classic blue and cream is the obvious choice, but here are combinations I've tested:

The body colour has the most visual impact — choose a shade that makes you smile.

Tips for Working with Chenille Yarn

Counting stitches is hard. The fuzzy texture hides your stitch definition. Your stitch marker isn't optional — move it up every single round. If you lose count, gently pull the fabric apart to see the stitch holes.

Use a smaller hook than you think. With the Sweet 2mm, a 2.5mm hook gives a tight enough fabric that stuffing doesn't show through. Going up to 3mm creates gaps you can't hide.

The tail chains curl — that's normal. When you crochet the ch-5 tails in Round 10, they'll curl a bit. Once the whale is stuffed and finished, gently shape them with your fingers. The chenille yarn is forgiving and holds its shape.

Change colours cleanly. Switch on the last yarn-over of the previous stitch. This single detail makes the two-tone whale look professional.

FAQ

How long does it take to crochet this mini whale? About 1–2 hours total. Rounds 1–9 go fast (maybe 30–40 minutes). Round 10 with the tail and fins takes the most concentration — budget 15–20 minutes for that one round. The decrease rounds and finishing take another 20 minutes.

Can I use regular cotton yarn instead of chenille? Yes — use sport-weight cotton with a 2.5mm hook for a similar size. The finished whale will have more visible stitch definition and a firmer feel. Chenille gives the softer, plush-toy look. Both work well for keychains.

What size does the finished whale come out to? With the Sweet 2mm chenille yarn and a 2.5mm hook, the finished whale is approximately 6cm (2.5 inches) long — the right size for a keychain or bag charm without being bulky.

Do I really not need to sew anything? Correct — the tail and both side fins are built onto the body during Round 10. The only "sewing" is weaving through the last stitches to close the body and hiding your yarn ends. No separate pieces to attach.
