Here's my "thingy" in use today at my show! DH made it with 2 pieces of wood perpendicular and screws going through the pipe into the vertical piece of wood. He used a 2" pipe, because that is what we had on hand. I'll try to get a pic of the bare "thingy" when I take the fabric off & do a better job covering it, now that the stress of my show is over!
I'm going to have him make me another one that's just a little taller to make a double row of headbands next time!
