This is easier to show than explain--- I add legs by putting on two wraps of thread ,lay two piecies of rubber on top take two more wraps. Pull one set of rubber leg away from and one set toward your body. This puts one leg to the rear ,one to the front on each side of the fly. No figure 8--that doesn't leave a space between the front and rear legs. You can cut the front legs shorter then the rear for hopper type legs. BILL
