I subscribe to the idea of not wasting. You don't need to use it yourself; if you can pass it on to someone else who will use it then it still is not wasted. And as stated here there are lots who will pay postage for unwanted fabric. and if you aren't sure if it is scraps or crumbs just ask- you will find out. I think I read here some will have the postage envelopes or boxes, and put their unwanted in;then post and send out. You can even have 2 one for the scraps and one for the crumbs. And if you belong to a guild you might even find a taker there.
