The warping peg set includes two clamps, a cross peg, and a starting peg. When you need to wind a warp chain, clamp the cross peg and starting peg into position with a clear path between them.
A warping board is more compact. Hang it on a wall or door, or rest the small one in your lap. Our 4-1/2 yard warping board measures 20″ w x 20″ h x 6″ d and weighs 3-1/2 lb. The 14-yard board measures 39″ w x 31″ h x 6″ d and weighs 7 lb.
