I recently pawed through all my scraps and relegated them to separate bins by color.
I figure this will help me make more crumb blocks.
I had to combine yellow with off white, orange with brown, and purple with pink, because there's a lot of overlap in those colors. Black and white are together as well.
Part of me wonders if this is too much organization. But the truth is, when I go into my scrap bin, it's usually for a particular color. So why not have scraps already sorted by color?
