Your shelves look beautiful! I'm so happy you made it work right - and I really like how you used plastic containers for your smaller pieces - I've just bought some comic book boards and realized some pieces just weren't going to work, but I didn't know how to shelve the small pieces so I could see them.
PS - for those who want to go cheap, acid-free, and cute, how about using cardboard wrapped in tinfoil wrapped in a piece of fabric with ribbon ties at the corners? I think I might try that as I have similar shelving.
