I still haven't made it back to my house, so here's the skirt I made, and as I have no sewing machine at my parents' , it's all hand stitched which has actually been really enjoyable!
I used the leg excess for the front patch, but it wasn't wide enough for the back so put this piece of fabric in which I think adds a bit of zazz. I'm thinking about putting yo yo's around the bottom, but not sure yet. It's a size 16, but as I'm a 12 it sits nicely on the hips. I think this will be a regulare wear with my superhero T shirt collection!
