This one is made out of a 6x6 piece of paper. It started out as a 12x12 paper. I'm not positive, but I think I purchased it at Michaels. The stamp was a cheap acrylic stamp from the Michaels $1 bin. It came with several other stamps...and quite honestly, I don't like how it stamps! ;o)
The "I love you" paper was purchased on clearance at Hobby Lobby a while back. It started out as an 8.5x11 sheet. I cut it down to a 4.25x5.5 piece of paper.
