I made DD a skirt out of a pair of Bernie sk8tr jeans - the ones that are really wide-legged and drag on the floor. They're black, and I used grey and white camoflauge fabric to fill in the triangle. The resulting skirt is floorlength and still drags along the floor, which is wretched when it rains but she loves it.

This is the first time something I've made for DD has been acceptable to be worn in public since she was four. She's 12 now. Wow, at 45, am I cool?
