Since I have been L/A for many yrs I have accumulated many pantos....I have them in a wooden bookshelf turned on its side and dh put separators inbetween....like a liquor box only a little bigger and I have them stacked my motif that way..i.e., feathers, swirls, baby, modern, flowers, leaves, etc..........has worked for me......they are hard to discribe, but look sort of like pidgeon holes or shoe cubbies..........
