Cell Phone Cozy (with window & accessory outlet)

Everyone knows that cell phones take a beating. After making and frogging Suss Cousins™ Cell Phone Case from her book Hollywood Knits, I decided to make some improvements. This is a great last-minute gift for anyone and it knits up super fast! Suss uses snaps to affix the flap to the body, doesn’t have a slit in the bottom of the case for the battery charger or earpiece accessory, and only does 1 row of crochet. Plus, her case is a bit bigger. She suggests using 1 skein Muench Naturwolle ($$$) or any soft, bulky wool in a multicolor.
