I went to an estate sale and for $25 I got 40 pounds of fabric (I weighed it) and a 3' x 7' cutting mat plus several patterns from the 30's. I cut the mat into two large pieces. I have one on my tall cutting table and one on top of a small dinner table that I use in my sewing room.
I recently had a garage sale in my front bedroom of quilting fabrics, etc., and I made $400.
