a good friend of mine built a holmegard which he backed with salmon skins- he used two per limb. it looked awesome- i think it offers better protection than snake- but maybe not as tough as rawhide.
i will get some pics from him today and post them here, and how he did it.
the advantage of salmon, is that the scales are so fine- we descale our fresh salmon here with a garden hose- no need to take a knife to 'em.
