Looking through my wife's give away clothes, I have run into pants made of 45% linen 55 % silk that has worked very nicely. As an aside, I was floor tillering a super thin ringed osage stave last weekend with some run outs, getting it ready for fabric backing. Drew up a splinter with very light very long string bending. In this situation, one can super glue a thin hickory patch on and hope for the best - which is what I have done. We'll see.
