Here's what I did:
I bought the following from our local Daiso store. You can find something similar at the local dollar store too.
a couple of rolls of magnetic tape
thin plastic case (used for holding reports)
I already had the label maker. You don't need one but my I wanted to keep track of the style numbers of the Spellbinder dies - my OCD tendencies are showing ;)
Figure out how you want the Spellbinders to rest in the plastic case. Then cut the magnetic tape to fit the area and tape it down. Add the style numbers.
Place the spellbinders.
Voila! you're done!
You could put another set of magnetic strips on the other side of the case. Hmm, I think I need to buy the oval set of Spellbinders to put on the other side...
