Terri at Three Martelles came up with this amazing altered printers tray for the holidays. She started with a 12" x 12" printers tray from 7 Gypsies, added Junkmill's 12 Days of Christmas collage sheet and decorative paper and popped the whole thing together with magnets so the collage cards can be swapped out. How clever! She sells the completed works in her Etsy shop, along with interchangeable card sets. What a versatile way to show off all that cool collage art.
