since i know people who happily accept boxes of pretty small peices of fabric i really don't throw any fabric in the trash- i keep a flat rate box under my cutting table & any piece of fabric i don't want to keep i toss into that box- when it's full i tape it up & send it to someone who will use them- there are always people looking for scraps for something-even if it's for stuffing dog beds- the only thing that goes in my trash is threads- frayed edges with nothing of substance left-
