Eric and I own an androgynous glass head, a lucky thrift store find. Over the years we've tried to come up with ways to fill it. Our ideas never pan out. I would love to fill this glass head with something awesome. Do you have any ideas? Please nothing super expensive; we once looked into filling it with vintage marbles until we realized that it would be a $100+ venture. I'm thinking more in the free or $5 range. Maybe it could be something we change regularly. Anyway, ideas???
