I think this is called a tri-fold card. I used the Happy Halloween sentiment, Jack-o-lantern cat and the tall pumpkin - which by the way has lots of different faces you can stamp onto the pumpkin - so cute! The grass is called grass border and fit perfectly on the edge.
What would you do with this challenge? We would love to see what you would do - Remember it does not have to be a card - you can make a layout or a 3-D project. Just use pumpkins somewhere in your design. You don't have to use Repeat Impression stamps but if you do, you name will be entered twice (2x) for a random drawing for a really nice gift certificate from Repeat Impressions. Check out Wendy's blog, The House That Stamps Built for the complete guidelines and link your project there.
Here is the list of Rock Star Designers who have made something to inspire you. Good luck - and I'm looking forward to see your projects.
Have a Happy Stamping Day!
