This is especially important if you are using rawhide because it will shrink as it dries. When you reach the end of the circle overlap the end of your leather or rawhide over the starting loop and glue it in place. Traditionally, sinew was used to weave the web. However, this is not readily available today in most areas. Most people use an artificial sinew that can be bought at craft stores, or for children's projects an ordinary string will do.
Some people also use thin strips of leather to weave the web.
If you use leather strips to weave the web, double the lengths given below for artificial sinew. If you are using artificial sinew you will want to cut a piece about a yard long for a three to five inch hoop, about two yards for a seven inch hoop, three yards for a nine inch hoop, four yards for a twelve inch hoop, and so on. If you are making a very tight weave, you will want to increase these lengths by at least double. The sinew will tangle easily so the best thing to do is to wind it around your hand or a small piece of cardboard in loops. At the slightest indication that it is tangling, stop and rewind the loops before you continue.
