Here is a great idea on how to renew your old clothes. One of my friends simply crocheted a border/edge from some leftover yarn and then sew it on an old skirt that she wasn’t using anymore.
Now she have a skirt with a completely different look and doesn’t have to buy a new one. What a great way to recycle your old clothes! If one use a little imagination and got some crafting skills one can really make a lot of cool stuff out of old clothes.

Here is a picture of the new old skirt with crocheted border:
