A great way to keep the paper stable is to mount it on a plywood (or foam
but I prefer the plywood) board, the same way watercolor paper is mounted
before painting.
1) Soak the paper in warm water until wet through
2) Apply paper tape to extend at least 1/2" along all 4 edges of the paper
3) Using a staple gun, staple the paper to the board through the paper tape
4) Apply wide masking tape to extend about 1/4" past the edge of the paper
tape, onto the paper.
5) Let dry
6) Coat with emulsion and let dry
Go from there. You'll see a lot less curling and distortion. It's a lot of
trouble but it's WELL worth it!
