You can purchase $1, $2, and now $5 bills from the Bureau of Printing and Engraving on sheets. The sheets come in sizes of 4, 16, and 32 bills each. I buy such sheets of $2 bills. I carry large sheets, folded in my pocket, and sometimes pull out scissors and cut a few off to pay for something in a store. It's just for comedy, as the $2 bills cost nearly $3 each when purchased on sheets. They cost even more at coin stores.

I take the sheets of 4 bills and have a printer, located through friends, gum them into pads, like stationery pads. The printer then perforates them between the bills, so that I can tear a bill or two away.
