These hand rollers are made for texturizing soft clay with a surface pattern. No handle is needed with these rollers. Just roll them like a rolling pin over the clay surface, can be used flat on a table surface or on the wall of a piece while still on the wheel. In the design samples below, the white areas will press into the clay and the darker areas will allow the clay to push up towards you from the background. . These hand rollers are made in Whitewater, Wisconsin USA.
