Using your cutoff wire, slice off a 2”–3” thick chunk of clay.
Run two fingers along the wire to remove moist clay.
Place your woodstrips on each side of the slab, no farther apart than the length of your rolling pin.
Rest the rolling pin on top of the covered strips and start rolling.
Run the rolling pin back and forth across the strips until it rides evenly along their full length.
Direct carving before firing is one way to decorate a handmade tile.
