For the claws on craw patterns, I've used the clear rubber strips found in craft stores or sewing shops. This stuff is used for making an elastic waist on a womans skirt and comes in various widths. It takes a colored marker well, has good action in the water and is practically indestructable. It also works well for the shell when pulled back over the dubbed, hackeled or cross-cut fur body. It is not expensive and has many other applications on different patterns. Let me know if you need more information on this product.
