Of all kinds.
Working on NICU donation quilts, photos soon. I also have an issue with batting scraps. Can't through them away. You know that stuff that you cut off after you quilt and before you bind? I have bags of long 4-6" batting strips. I salvaged an old fleece nightgown from the years before menopause lit my internal fire, and make the quiltorium kitties these little pillows to sleep on. Clyde loves his. It's a little bigger than the other one.
How about you, do you obsessively save stuff like this? If so, what do you do with it?
