Hobby Lobby is a great place to get anything in the crafts field, as they carry virtually anything you can think of, from beads to shrink wrap, and from model airplanes to modern art.
I particularly enjoy going to the discount section, where damaged items go, and to be honest, some of the stuff Is pretty beat up, but other things might just have a ding or a scratch, and I can save up to 50% (just have to be handy enough to fix things up a bit).
It's a fun place to be, if you do anything artistic, you will probably find yourself here on at least a couple of occasions!
