I've been storing my thin dies in the thicker original CD cases for a while but now I have a collection of cases. What to do? See this post on Thin Die Storage. My niece gave me some of these cases ready to go last Christmas. What a great idea!The challenge is to have the CDs easily accessible and find the one I need quickly. Now I have them all organized and labeled on the top. I can just pull out a bit and read the label. I'm really happy with this storage solution.
