14 ½ - 14 ¾" Height x 3 ½" Width. The seam rubber is a tool for rubbing or pressing a crease into the sail fabric prior to seaming. To be effective, the seam rubber had to be hard and was usually made from bone or lignum vitae (tropical type of wood). During the sewing of a sail, the edge of the sail is folded and a crease made.
This is done by rubbing the seam rubber over the crease a number of times while applying force, in the same way as a paint scraper, so that the crease remains flat on the sailcloth. Once the hem has been creased and rubbed all the way around the hem was sewn up.
