I've been searching for a way to display my hats that's both decorative and practical. I had considered using styrofoam balls cut in half, but I don't know what to attach them to, or how, in order to affix them to the wall. I'm also afraid that the foam won't be sturdy enough for long time use. Please, if anyone has any better ideas on hat display, lay it on me. =) Thanks in advance. ~F
