One Sheet Wonder idea another Demo (sorry, I did not get her name) demonstrated at SU Regionals recently. I liked her simple way of cutting up the 8.5" x 11" sheet of stamped cardstock -- so much easier than any other OSW I had seen. It's just 2.5" squares, which gives you 12 squares to work with and two 1" strips left over to also use.
I get bored easily, so I varied my layouts but if you want even quicker cards, stick to just one layout!
