I try not to even think about it anymore. I lived all my life with the "waste not want not" attitude first from my parents, and then my husband. I got so tired of all the stash of junk they had created that if I want to throw something out that I know I won't ever use, then I throw it out. Although I must say that the other day I did make some potholders from scraps. And I find I am saving triangles that I would normally throw away. As far as selvages and 1" strips, out they go. I have enough bins to sort through now.
