Phone cozy

 
I needed a quick project to practice cabling and my phone needed a cozy.

The number of stitches and rows to use depend on the weight of the yarn, the size of the needles and, of course, the size of the phone.

Here's what worked for me.

I used BeBe Cotsoy yarn (20sts+s6rows to 4"/10cm) with size 6 dpns.

Pink body:
Cast on 32 stitches and join in round
Round 1: p2 k4 p2 (repeat 4x)
Round 2: p2 k4 p2 (repeat 4x)
Round 3: p2 cf4 p2 (repeat 4x)
Round 4: p2 k4 p2 (repeat 4x)
Repeat above four rounds to desired length. (For me, it was 9, for a total of 36 rounds.)
Bind off.  Fold so that there are two cables on each side and close up the bottom using a whip stitch.  Weave in loose yarns.

Green flap:
With the front of the work facing, pick up 6 stitches.
Row 1: k6
Row 2: p6
Repeat above 2 rows 5 times for a total of 10 rows
Row 11: k3 yo k2tog k2 (This makes the button hole.)
Row 12: p6
Row 13: k2tog k2 ssk
Row 14: p4
Row 15: k2tog ssk
Ro2 16: p2
Row 17: k2tog.
Cut yarn and pass through last loop.  Pull tight.

Making up:
Using phone as a guide, mark where button should be placed on front of cozy. 
Sew button on with a piece of felt on the inside of the cozy.
