I keep track of the fabric I use - estimate by size how much on each quilt. and keep track on a sspread sheet for income tax purposes. figured last year I used over 2400yds of fabric on 108 quilts for Linus. plus 1200 yds of batting. I figured out how much for binding too, but forgot what that figure was. I didn't keep track of the thread. that would have been too much like work
