I have used Tyvek for wing casings a la Gonzo, and I love it for stoneflies. But I also started using it for legs-- I use an Xacto knife to cut very thin strips. Has anyone else tried this? I probably won't have a chance to thoroughly test out these patterns so I am curious to hear others' thoughts.
James, some earlier versions of my Tyvek stoneflies did incorporate Tyvek legs a la Paul Schmookler. The method I used was to cut the entire set of legs from a single, folded piece of Tyvek (paper-doll style). The effect can be very nice. I would recommend sealing the legs with a good coat of Flexament or something similar. Otherwise, the Tyvek can sometimes separate at the tips with hard use.
