I made some "We've Moved" cards for a friend that is moving this summer. I used a large sunflower stamp and was afraid after the sheet was sliced up it wouldn't look so good. I think they turned out great! I took the pictures with my son's new camera, so they aren't the greatest as I don't know how to use his camera. You'll get a good idea of what they look like though.
Got me to thinking it might be fun to have a "One Sheet Wonder" swap. Have each person pick a sentiment like "Thinking of You", "Happy Birthday", or "Thank You" for examples and make 10 cards. Then depending on whether there were say 5 in the swap or 10 you'd get 2 of each design or 1 of each design.
The new cards are in my cards album.
