I love, love, love crafting with beads - and although we traditionally string them on things, that doesn't mean they don't work on cards.
I really like Erin's take on the challenge, particularly that it's a real "think outside the box" moment.
See the beads? Thanks to Mardi Gras, Erin had a string of beads on hand, and they totally work in the background!
As long as it qualifies as a bead, it fits for the challenge and you can use one or many on your card.
