I found this skirt in a charity shop. It was mid-calf length, tight and khaki and not terrible pretty - so, I chopped off a few inches so it was just above the knee, added triangle panels at the sides, put pockets on the back, sewed on some zips and trimmed it all with ribbon. Oh, and stencilled the patch on the back pocket.

This is the back:

Front:

Pocket: (sorry you can't see it very well)

I need to finish putting ribbon on the front pockets, but it's near enough done!
