Textured Block Set

Here is what Bill has to say:
"Add an interesting texture to your coiled handles by rolling coils of clay between these two non-stick corrugated boards. Position the boards at different angles and directions to produce an assortment of great textures: linear cross-hatching, twisted spirals, circular rings, straight-line grooves, and more. The corrugated surfaces are sized to create textures in the correct proportion used for functional pottery. Decorate casserole handles, mug handles, hand built knobs, foot coils ... Your search for a sturdy corrugated texture tool is over! "
