To knit this pattern:

Cast on an uneven number of stitches.

*K2, P2* repeat these 2 stitches until there are 3 left on the needle. To end: K2, P1

Repeat this pattern until piece is at desired length.

I didn't end up doing a lot of tapering for the flap of this piece, but if you want to do that, start and end the row by knitting the first two and last two stitches of the row together. This picture shows how I picked up two stitches on my needle.

Note: I used two balls of yarn for this project to get the dual colors, so it might look like 4 stitches, but it's really only 2!

Also please ignore our ugly carpet at work :)

It wasn't really easy to take pictures of making the button hole, because I just bound off one stitch in the middle, but here's what it looked like when the whole thing was done. (I put red paper under it to make it easier to see). Remember to add back on the stitch you bound off to make the hole!

Now you're ready to sew up the side. Figure out how deep you'll need the pocket to be, fold it right sides together, and thread your yarn on a tapestry needle.

Like I said, I used two balls of yarn to make this project, so I sewed it up with two pieces as well.

You're going to sew through the piece. In this picture, I didn't pull the yarn tight so you can see the way I've gone through it. Obviously when you do this, pull it all the way through! Do this down both sides.

Turn the piece inside out, and now you're ready to sew on the button! Slide the phone in the case and mark where the button will need to be so you don't put it on too high or low. Once the button is on, you're done!
