I cut this baby in a bathtub at 5" out of cream cardstock then did all my layers. I cut an extra tub for the back but didn't glue it completely. I inked the bubbles with some baby blue then covered in Diamond stickles.

I am holding a workshop at Hearts-n-Crafts this Wednesday for $5. Come by if you live in the area.
