Karlyn uses these rubber pads to carve out custom stamps.
We recommend sanding the smooth rubber pad with sand paper to roughen the surface so it works better with your watercolor paint. This step is not necessary for acrylic paint, maskoid, gesso, etc.
Speedball brand. Use with water soluble products. Easy to cut, flexible, and will not crumble or break. Use slightly warm iron to transfer images: pencil drawn, newsprint, freshly printed ink-jet and laser-print images. The rubber material is easy to carve.
