Perfect for all types of crafting materials - The Sculpey Tools 3 piece Floral Silkscreen Set is perfect for use with all types of crafting materials including: polymer oven-bake clay, air dry clay, and pottery clay. Tips for using the Sculpey Tools Floral Silkscreens - - The screens are so easy to use! Simply roll out a sheet of clay, place the silkscreen shiny side down on the clay and burnish it down making sure there are no air bubbles. - Then squirt some acrylic paint at the top of the design from edge to edge and use the included squeegee at a 45° angle to drag the paint across the screen. - Now you want to get the silkscreen into a basin of water right away so that the paint does not dry on the screen. - Allow to dry and then you can cut out shapes for your final clay creation and bake in your home oven. - The smaller designs are 1.75" which match one of the Sculpey Tool Circle Cutters and the largest hump on the Sculpey Tools Hollow Bead Maker. Versatile Creativity - There are 7 designs in the silkscreen pack! Perfect for all of your DIY crafts, jewelry making and mixed media projects!
