It's getting harder to find 100% wool. Most suits are a wool blend now. About five years ago I found a shop that had wool fat quarters on clearance. The shop was not selling that line anymore. It was Sue Spargo wool fabric. Even at the clearance price it wasn't selling very fast. The shop owner said if I would buy the complete bundles she would take 75% off the clearance price. Heck yeah! I got four fat quarters of every color and bags of wool strips used for wool rug hooking and have it stored in a big bin waiting for me to get inspired. LOL
98% of my stash has come from clearance sales and going out of business sales. I search for these sales like searching for gold. I have given a lot of the wool fat quarters away to members on this board.
