I saw this in a book yesterday "Gift Ideas" AWESOME book, I should have bought it.
They had a sample of a paint can done collage style but they offered ideas you could use the can for (decorated differently of course), one was an entertainment can. Put a pack of popcorn, candy and a blockbuster gift card for movies; something along those lines.
They also recommended using SB page instead of CS b/c it's difficult to get it to stick arond the can.
Other ideas in the book: A baby shower can (for someone expecting of course), a birthday can. I think any of the survival kits we do in the cello bags would work great with the cans, you just need to expand whaT goes in them. I'm thinking a PMS can! Nothing like a can full of chocolate to lift your moods.
