Here are two of our unit swap items from our October meeting that I forgot to post for you. I'm sorry they're late, but the same idea can be used for the Holidays also, just change out the papers.
This is a card box that opens to reveal chocolate! It uses the August Stamp of the Month "What a Hoot".
These cute cards use "Trick or Treat Sweets" (B1460) stamp set. I could see these as Treat Toppers also for Halloween.
