What can I do with very small fabric scraps left over from sewing projects? Use vs. throw away?

I've gotten into sewing lately but there's one thing that is sort of bothering me... I end up with a ton of very small and/or very awkwardly shaped fabric scraps. I'm trying to live "green" and it just seems wasteful to throw away these bits of fabric, however I can think of no other use for them (besides quilting, but I am not a quilter and I know no quilters). Any ideas for ways I can use these small/awkwardly shaped pieces of fabric? Thank you!
