Just the other Day someone asked the question?  What do you do with all the scraps from wool projects?  I save mine because you never know when a small snippet of wool can make a flower, a heart, perhaps a leaf or stem.  I have these bags available for sale as long as they last.  Oh, don't worry, I save a ton of them for me too!  Each bag is 9 x 12 inches and stuffed to fit as many pieces as I can get in it.
