These Skeewbackers are constructed from a rigid polystyrene foam core sandwiched between waterproof membranes. They are perfect for your unique mosaic to enhance your home, kitchen and to give as gifts.
Don't forget your NippinSquares which are stained glass squares perfect to cut small and use on your backers.
For trivets and coasters, you can paint the edges and backs with acrylic paint. Then glue the cork to the back after the paint is dry. Best to put a hot pad between hot dishes and trivet to give added protection from the heat. Hand wash only.
