An innovative peel-and-stick self-adhesive foam trimming bat.  This bat is ideal for trimming large bowls and plates without using a coil to attach the piece to the wheel head.  The foam bat sticks firmly to all types of wood and plastic 14 inch bats. Once applied to the bat, the foam grips the rims of leather hard pieces and holds them in place for trimming.  Items can be centered easily using the concentric rings.
