Thank you, Gemm! This thread has really helped me change my mindset about buying fabric.
My main stash projects from last year were a BOM led by Andover designers, and what turned out to be a rather fancy mystery from Bear Creek. I bought only border fabric for the mystery, and will need just sashing and whatever I use for border for the BOM. Since I finally experienced the thrill of using stash only, I hope to repeat the process! Here are my blocks roughly up on my wall.
