I bought black silk for the back of this red oak board bow. I sanded the back of the bow down to about 400 grit. I put the first strip in a bowl and saturated it with Titebond III. I used it to apply a tack layer to the wood surface. I then had a blast untwisting and flattening out a strip of silk saturated with wood glue! It is on there and mostly smooth still I hope! I decided to try to do the other end easier. I spread glue on it and then laid the silk in the glue. I then saturated the silk with glue while it was in place. Easier, but still not easy or a perfect smooth surface achieved.
It is clamped up to another red oak board with a layer of static plastic wrap between them. I think I should have used a cushion layer of some kind on the protected side to provide even pressure across the entire width.
I don't know if all backings are like silk seems to be, but it is almost as bad as the cling wrap about rolling up, sticking to itself, and not wanting to straighten back out it seems.
Hope it turns out better than I suspect it is going to!
