I adopted a policy for myself a couple years ago and is working pretty well. I try to use something from my stash for each new thing I get. I was pretty proud the other day when I came upon 6 yards of fabric from my stash to use as a backing for my grandson's fleece blanket I am making for him to take to college this fall. I was able to use the whole thing, so no scraps to add to the scrap box. I figure that 6 yards was good for at least 6 yards of new. HA! HA! HA!
