I need a little help. This is my first time to post anything, hope I'm doing it right. Anyway, I am making a legal size folder for my stepson and I have already put the final finish of Neat-Lac on it when I realized I did not dampen tthe middle section to fold it over. I did and got too much water, now I have a water stain along the edge which, of course shows on the front and not the back. Also, I had already glued in the stiffener on the front. Does anyone have a suggestion of what I can do?
