Techniques For Using A Blow Dryer To Dry Paintings Quickly
Paper is porus!
As you deposit paint on the surface, the moisture also soaks through your paper. If you want your paper to lay flat don’t forget to dry the back also.
I point the dryer under the edge of the painting, forcing the warm air under the paper and drying the underside. I rotate the board and do this under each edge for a few seconds each.
