Dull pins though I've been known to sharpen a sewing machine needle. Icky fabrics become the foundation to string or crazy quilt blocks. Anything smaller than 1.5 wide unless I happen to be piecing minatures. Tiny pieces of batting but never strings of batting. I don't buy much anymore so everything I keep fits in 33 9x13inch baskets. Unless I'm working on scraps, then its everywhere. Good question.
