Fish skin sewing "Salmon skin can be tougher than Gore-Tex or as soft as velvet. And everything you need to transform the scaly hide into a workable piece of clothing or art material can be found in your kitchen." My beautiful friend, Audrey!
If you need to pitch a tarp or tighten a fly, you can make an impromptu tarp clip from a split twig, a matchstick and a bit of string. Works best if the clamping part is long enough to go over the folded edge of the tarp.
