LOVE THIS THREAD! I made a scrap quilt for my granddaughter of scrappy squares put together with white sashing. I tried to make the scrappy 2 inch cornerstones with 4 or more pieces, but one had 11 pieces.
I have a waste basket with a small pillowcase-like lining (trash fabric). All the "lint" goes in there for cat pillows for Kathy's local cat shelter. When it's full I sew it shut. Kathy says just throw them into her garage.
Don't forget the BATTING! I keep a pillowcase-sized bag nearby when I'm working with batting. All small scraps go in there. (I join larger scraps to make more batting). When that bag is full, I make a nice cover for it so I can donate it to the local food pantry or homeless shelter.
