What can you do with old wire-wrap sockets? Turn them into frogs. Flower frogs, that is, which are used for holding flower stems at a particular angle without the support of a vase edge to lean on.
If you happen to have a socket like the pretty blue one, no further work is required. It is very much like these frogs and, even more so, these kanzan for Ikebana. More commonly available sockets can be put in a piece of perf-board so that flower stems can be slid onto the pins.
Socket frogs are not as heavy as traditional lead and brass frogs, so use stones or glass weights to hold the frog in place and cover it. Add water and your arrangement is complete.
