Phone Cosy Pattern

I made a cute phone cosy for my Sony Ericsson Mini XPro. It is a cute little phone that I've been carrying around in a sock! This is much nicer and didn't take long at all. I started it on the train yesterday when I went to London to see Sucker Punch at the IMAX.  It's a fun film - not essential viewing but full of explosions and girls kicking butt.

Phone Cosy Pattern:

(a few more edits on 01/05/11, Thanks Jody!)
Use sock yarn and 2.5mm dpns
k = knit
p = purl
k2tog = knit two stitches together
k1b = knit one through the back of the loop, sometimes written as k1 tbl, this results in a twisted stitch, a video here

Cast on 39 sts
Join and begin knitting in the round
Rnd 1: p3, k16, p4, (k1b, p1) 8 times
repeat rnd 1 until cosy measures just longer than the phone
Decrease:
Rnd 1: (k2, k2tog) to last 3 sts, k3. 30 sts
Rnd 2: knit 
Rnd 3: (k1, k2tog) around. 20 sts
Rnd 4: knit

Rnd 5: (k2tog) around. 10 sts
Rnd 6: as Rnd 5. 5 sts
Cut yarn and pull through remaining sts

My phone has a circumference of 13cm and a length of 9cm. The same cosy also fits around my ipod classic which has a circumference of 14cm but it's a bit short. The pattern can easily be adapted for larger phones.
