Yeah, the paper will be unnoticeable. think of it as a 3d tracing paper for the real end product.
Also, side note, once you mix up the resin, there isnt a thing in the world that will stop it from drying. And being outside doesnt give any real advantages. Just a quick heads up. Allthough, I've found out that if you leave it over the AC unit giant fan thingy while it dries, the smell goes down noticeably.
Cheers.
