I would say I topped out between 300 to 500 yards. I am down to 75 to 100 yards right now. When I inherited my first 'stash' it included at least 100? 150? yards of silk. I couldn't sew it for years, I just wanted to touch it and look at it and touch it. It is my goal to sew down to the nothings so I can justify new stock. It has been time to let go of most of it for a long time. I have dribs and drabs of the silk, lots of baby quilt pieces but I have almost sewn all of my large yardage pieces. It is hard to let go of it. I can't throw scraps away. I have learned to buy a piece of yardage if it really calls out to me because I won't see it again if I pass it up.
