To make the baskets coordinate with the room, I double-mounted some fun scrapbook paper onto cardstock. I printed numbers in text boxes with bold borders on the computer and glued them onto the scrapbook paper.
You'll see in the photo below that they seemed to be missing "something." I liked them, but felt they needed to be tweaked a bit.
So I took a black marker and quickly outlined one layer and it was just the "POP" that it needed. I had contemplated outlining the card as a whole, but since they were being attached to black baskets it wasn't necessary.
