Oh, that's hilarious Dee!!!!!
Here's what I would suggest. Find one of those shower curtain rings, the big circle ones that the shower curtain hangs from. Then see if you can find some red and white striped fabric. Make like a tent that hangs from the shower curtain. (You can sew a curtain like hem in the top and put the shower circle through it so the fabric hangs down as far as you want.) Then you could take some felt and cut out letters as big as you want and glue them (or sew) to the "pop-corn tub" that you have contstructed. Figure out how to get the thing to hang on Mick, and there you have it Pop-Corn.

I can see this in my minds eye, I hope I've explained it OK.
