I thought that I'd throw this out there since I'm pretty new and have already picked up a lot of awesome pointers from this board and wanted to give a little one of mine.
Pennies can be a hell of a lot of fun. Go to a hardware store like Harbor Freight (my favorite- and always an inspiration) and pick up an industrial handpunch for metal. It's less than 20 bucks and comes with multiple punch sizes. Punch some holes in pennies and have fun! Here's a wristband that I made- you can make all kinds of jewelry- earrings, even handbags or "change" purses
if you want to. This is the one I kept for myself- but they look even better when you have 3 rows in thick leather and use laces to tie it corset-style rather than snaps.
One more thing- if you want all shiny pennies, or to do a checkerboard-type pattern, childhood science experiments tell me that salt and vinegar clean your dirty copper wonderfully- don't leave them in the concoction too long, or they turn black with green build-up (which is also cool). In addition- sprinkle the concoction on the pennies, then wash it off for polka dot pennies.
