Made this skirt for my sister's birthday. Bought a load of t-shirt from the thrift store (pink and black, cos she loves pink and black!).
Made a long triangle shape from paper and cut out the shape from the t-shirts (enough to fit).
Made the seams on the outside for a bit of extra funk! Added a little pocket and a star.
Made a simple elastic waist by rolling over top and sewing in elastic to fit (no zippers - yey!)
