Long story short. I oil painted ontop of a watercolor painting I did. The matt that the paper was stretched on came loose from the table, now the oil painting is warped. The painting is large, pic included, how can I get it flat again without damaging the finished painting. Pic included, painting is not finished yet, critiques on the painting are also welcome
I just want to ask why did you paint oil on a watercolorpainting? Is the oil painting part large? Im pretty sure oil on watercolor paper is not archival, and the drying oilpaint will create too much tension on the paper so overall i wouldnt do it.
