I'm sure you will find lots of patters and examples to do one sheet wonders. And yes, the 'one sheet' is the piece that you cut to make the cards, or 3-D item - you can do scrapbooking with it too. Its lots of fun and easy to do. Change your stamp set and you get a whole different look to your cards! They make great gifts if you want your cards to all coordinate. Just add different sayings. Anyway, this will keep you busy for a while!
