I bought one at my lqs and it was 28.00 on sale for around 19. But its not very big. It works ok but not very big for what you pay for it. HAve heard of using the oven liners you can get them at the Christmas tree Shop for $5.00 but haven,t heard how they work. You must have to tape them down so they won't slip around. If they work it would be slick because you could cut it any size you want. You have to cut a small hole for your needle.
