Finally found my ink blending foam storage solution! Although the pocket pages don't lay flat (rather they curve a little) with the foam inserted, I still love this solution. I didn't need to label the foam because my inks are in the mini distress ink storage tins, which also have 12 compartments. I have the inks and the pads lined up in a coordinating order between the the pocket pages and the storage tin for easy matching.
These pocket protectors are also the perfect size for Jennifer McGuire's 2"x2" ink swatches for those of us with a smaller ink collection than Jennifer (she uses larger pocket protectors with 20 slots per sheet).
