I was painting again today and came to the point of taking off the masking fluid. The stuff wouldn't come off! It has soaked into the fibers of the paper and I'm stuck with it. Since it's yellow on all the white highlights I might have to start this one over (if I feel like doing it again). I am particularly annoyed because this is the first time it has ever happened to me. I bought a more expensive kind of masking fluid than usual to try it out. Needless to say I won't use it again. :( I might try using white paint over the spots to see if I can save it but it might be beyond saving.
