OK Here we go!
Cut a half moon shape out of each side. You can make the moon as small or as large as you want.

There may be a little overlap where the middle "guts" stick out into the sides. Cut the extra layers out.

You only want 4 layers when sewing the elastic.
Start on 1 end and put your needle through the fabric and the elastic. I used lastin, but regular elastic works fine.
Using a zig-zag stitch (3 step is better, but regular zig-zag is fine too) stitch down and backstitch. DO NOT pull on the elastic until it is sewn in and backstitched.

Pull on elastic while sewing down the side. Elastic should be between the 4 layers.
Should look something like this

Finish the sides as you wish- serging is best, but zig-zag or overlock stitch is fine too. ;)
