hi Kelly,
i like to saturate the silk( glue side) with glue, and spread some glue on the sized limbs( as you did) then place the silk on the limb- that way i get good saturation all the way through. dunno if its correct- just what works for me. i have used silk on a number of bows now- and i really like it- just where i needed the extra security on the back, one was a 1/4 sawn hickory backing strip on a HBI bow , that always seemed to lift microscopic splinters/ burrs/ fluff, no matter how much i sanded it- so put a layer of silk on it!
one was a bow that a mate was building at my shop, and he scorched the back a wee bit while heat bending it, so we scraped it down to reasonable wood- and silked it- still shooting well today in aus- and he had killed a few goats last time i spoke to him!
i like the stuff.
but also really like rawhide too!
