I find I have amassed alot of Papertrey dies and therefore, have tons of die cuts to store. The best system I have found to do this is this case I found at Michael's. I think it is designed to hold photos, but it works great with die cuts too. The case holds 12 individual boxes. I store the case on the floor right beside my chair I sit in when I stamp. I will reach for it and see if I have the die cut already punched before I'll get up and cut new ones. It's very handy for me. I have a couple plastic tackle box type containers too, because this one got full pretty quick. They are nice for border cuts because I can put the dividers wherever I want. So it's nice to have two alternatives.
