Thanks everyone! I finally came up with a great solution. A family member was quite emotional at the thought of me selling these and I couldn't bring myself to toss them so this is what I did!
A votive holder fits right into the opening. It's very beautiful when lit up.

The variegated threads are not usable but they make a lovely display in the curio.

This is a lighted curio that holds all of these mementos, including a crocheted doll dress from my Great Gram and a wire base from my dad and some baby things that my daugthers outgrew.
