I love projects that finish up quickly. They give me the immediate gratification of completion and allow me to move on to a new project. This is why I personally prefer crocheting to knitting. For me a crochet project works up quickly and while I enjoy knitting, it takes me longer to complete. This is also why I like sewing projects. I'm not one to sit down and whip up an entire quilt but I do like stitching up quick little things that could be sold or used as gifts. Small sewing projects can be a great way to use up that stash of extra material we all have hanging around.
Here are some links I found with ideas on how you can use up your stash and whip up some cute things in little or no time:
