Carabelle Studio Coulissant 1 Des Ronds Stencil Set, or "Set Coulissant 1 Des Ronds" meaning Sliding Set 1 Rounds in French, is a creative stencil set designed by Alexi. The set includes two stencils that can be cut apart so they are no longer connected. Here's how they work: Place the hooks from one stencil inside the slits in the other and then over. Now you can slide the top stencil up and down, creating new designs. The templates are approximately 7 x 4.25 inches each and are full of large and small circles, allowing you to create hundreds of unique and imaginative designs.
