[cactus-jess.livejournal.com]

I've been trying (desperately) to find a 1/2 inch paper punch. i remember reading this would make my marble magnet/push pin making MUCH easier, and i believe it! However, I can't seem to find a 1/2 inch paper punch. does anyone know where i can find one, preferrably online, as i've already searched the local wal-mart and craft stores? is it a 1/2 inch circular paper punch i need, or is there something else i shoulc be looking for?

thank you so much!
