Almost three weeks ago I began a painting with oil pastel on wallis using turpenoid natural as a blender. Last week I finished the painting...still using some turpenoid to blend. Today I checked it and its still 'wet'. Not wet like the oil pastels usually are after a week....but wet like the turpenoid is still not dried out.
Has anyone else noticed a lengthy drying time when using turp natural? Or could it be the texture of the Wallis keeping the turpenoid wet longer? I wanted to give this to the church which provides my Friday art group a place to meet each week for their annual fundraising auction....but it was too wet. Instead they got the autumn landscape that I did for the TOPP.
