Beer Mugs

I try to make a cute gift for my 2 friends who want to make cute Margarita glasses for us. I also need to find 3 Beer Mugs. The problem is, I can not find them individually and if I do them in glass and I do not drink because we tend to fall too. The only place where I can find it at Crate & Barrel, but there are none near me. Does anyone know where I can find some?

I've seen acrylic margarita at Wal-Mart the other day and I think I saw them at Dollar Tree. Incidentally, did you embellish? I know what you create! Good luck!
