It took me a while to come up with a plan on how to create the talons for Varian Wrynn's bracers. Really, the talons are what kept me from building the bracers before now. What I ended up doing was cutting a piece of pink insulation foam and sanding that into the general shape. The talons on the bracers are built from shaped insulation foam, then covered with Worbla.
On the left us my first attempt (without a foam core) which really didn't work. It looks like a tube with a point on the end. :)
