Finally a practical use for all of those horrible vinyls we see at the antique stores (you know, the discs that no one really wanted to listen to in the 70s and 80s, let alone NOW). These would look really cool when the basement is redone.
Upcycled vinyl records! You can use the microfiche catalogue too to cut out butterfly and dragonfly etc! Out date floppy dish will be great too! For CD or DVD, you can saw the half shape and glue them together! Use colour paper, if you just need a quick deco in the Library!
