Here is a picture of the inside:
Not counting the spot where I keep the font cartridges, it will hold 54 cartridges. It works really well for me and I am able to quickly access my cartridges.
I also recently went on a Cuttlebug folder buying frenzy and needed a way to store them. I found Okieladybug's folders (A2 Cuttlebug Folders) and wanted to use her file, but I don't have either of the cartridges she used. So, using her measurements, I made my own file using the Opposites Attract cartridge and this is what my new Cuttlebug storage looks like.
Tomorrow (today I guess!) I am going to Michael's to get two more Jetmax cubes to finish up my teeny, tiny corner of the living room so I should be organized completely this week!
