I hear you about running out of room. I quickly ran out of room also. Then, I converted an old foot locker into our toy box. I keep quilts on top of it so no one ever peeks in.

For my glass toys, I purchased a cloth lined basket and to keep them in. Also, to keep them from banging into each other I wrap each one in a small dish cloth. Not ideal for knowing which one is which, but it is the only thing I could come up with.
