Sounds very similar to my experiences with gelatin.

Hmmm ... not sure I want to know any more <smirk>. I'd guess you meant to

Yes, you probably need to size the paper first.

Sounds interesting! My understanding is that a hide glue is basically
just a lower quality form of gelatin [A.G. Ward and A. Courts, The Science

it might work. I'd be interested in hearing about any more experiments
you do.
