Customized Cell Phone Cover

This is a picture of my daughter's cell phone cover. I didn't have a pattern to go by so it was a little more difficult to make. I measured her phone and the first two times, she didn't like the lettering and the second time, the cover was too small. Third times a charm and I got it right. Then she informs me that she wants a strap on it. Well, I had to improvise since I had already sewed it all together. I sewed a piece of velcro as the strap and it worked out all right. Next time I'm going to make a strap out of fabric before I put it together.
