Cell Phone Cozy

I looked high and low for cell phone cozy patterns.. all anyone does is crochet or knit them.. and they are VERY sweet.. but what's a girl to do who can only ( just barely) sew?

this is a pattern I found for sewing cozies but I dont like it..

look how FABULOUS this one is!!

thisis what i want to make.. which looks easy enough. I suppose it's 2 pieces of material sewn together and flipped inside out with a lining (much the same way as a regular tote bag) with bias tape for edging and a strap that is sewn on the side and buckles at the front. I guess I can make my own pattern for it and I might even use some batting to make it soft and a little puffy..

will update when I do!
