Made to fit HTC and Samsung Galaxy S2 phones.

1) Cast on 24 stitches and join to knit in the round.
2) Using Magic Loop or whatever circular method you prefer, work in K1 P1 rib until you reach 4 inches in length.
3) Knit 1, bind off the next 10 sts, then work the rest of the round normally.
4) Next round, K1, then cast on 12 sts using backward loop method, then work the rest of the round.
5) Next round, K2tog, p1, k1 p2tog, work the rest of the round normally. Continue in rib until piece measures about 5.75 inches.
6) Graft the front and back sts together at the top and bottom. Use white cotton to embroider eyes.

To make antennae:
I used a crochet hook and joined the yarn to the top of the piece, then chained 3, then I turned the work horizontally and slip-stitched back to the work. I used a needle to darn the ends down to neaten them up.
