One of my favorite types of cards are shaker cards, and I've been having lots of fun with the kits by Jillibean Soup.
The rainbow stamp is from an SP & Company set, and I colored it with Copics. The sentiment, from a Flourishes set, was stamped on shiny white paper, and the cloud-shaped shaker was filled with tiny gold stars. I cut the card base to make a square card, and punched a border on the bottom with a MS punch. I backed that with more shiny white paper. I've gotten several compliments on this card, so I think it's a design I'll go back to.
