Okay, well, I'm making this skirt, but it's not quite done yet, so sorry! I don't have pics of it. But I will add them later. Anyway, this is what the finished project looks like, except shorter:Tutorial:
After that, hem the jeans so that no raw edges are showing in the finished product. Then, sew the fabric and the jeans together, wrong sides together. After that, hem the skirt and you're done!
(Sorry the pics aren't the best quality.
