It's been one year today since I bought any stash fabric.
I did have to buy a 1/2 yd to finish a quilt but since I used it all up immediately I don't count it.
I've donated 1/3 of my stash to a church group, and I've used up some yardage on my own during the year. I figure it'll be another 2 years before my stash is gone. Never again! I'll buy as needed only.
