There was a fad years ago in which you slice the Osage Orange and bake the slices, then use for art projects, like make flowers or put on wreaths. I always thought the fruit was interesting, and it seemed a waste that there were so few practical uses for it.
I've seen those, in potpourri etc. But I always though a lot of them were made from Bael Fruit (Aegle marmelos) (a citrus relative native to India which is mostly rind and pith) But now that I think of it a sliced Osage orange WOULD look the same.
Sliced thin and dried then painted. I had a co-worker who wore a lovely pendant made from osage orange fruit. I could see them as part of wind chimes as well.
@TheSeedObsesser Both walnuts and osage orange self propagate like crazy in the fence line. Anyplace one drops or a squirrel burries it. You should have no trouble growing some. The hedge apples is slow growing.
