Chain Chomp Keychain

I am easily distracted and I procrastinate a lot. I was on Pinterest (naturally) when I came across a key chain cozy in the shape of a fish. This was enough to make me think of Super Mario Bros. and instead of finishing the hundred other projects I’ve got going, I decided to make a Chain Chomp keychain:

First, crochet the body. Make two pieces.

Round 1: start 6 sc in ring but do not join because you don’t want to make a circle.

Round 2: ch 1, turn and increase in each stitch (12 sts)

Round 3: ch 1, turn, [inc, sc] to end (18 sts)

Round 4: ch 1, turn [inc, sc in next 2 sts] to end (24 sts)

Fasten off and leave a long tail for sewing. Make the second piece and weave in ends.

With white felt, cut out a row of small triangles to make the teeth and sew onto mouth. Cut out the eyes with white and black felt and sew those on as well.

With a yarn needle sew completed pieces together, making sure key fits inside.

For the chain I bought a key chain from the dollar store and with pliers I took it apart so I’d be left with just the chain.
