Challenge to self: I was working on my daughter's birthday card away from home, and challenged myself to see if I could use up ALL of  the scraps.  I started with 3 12x12 pieces of patterned paper, and laid them out, pieced them together, and got the following cards.   All I was left with in the end was a single 1.5"x2" piece of scrap.  I made all the fronts, and added them to bases and embelllished @home.  Pretty cool!
