I paint with soft pastels on UART sanded pastel paper. According to the description of the paper, there should not be need for fixing. Yet, my framers complain that I should fix my paintings, and several times they have also smudged the painting even though I asked them to be very careful. Of course, that’s most depressing. For this reason, I have tried several fixatives (Winsor & Newton, for instance) and got disappointed every time. Even if I try to apply it very lightly, the paintings get darker or even spotted, and the nozzles get clogged. Some of my paintings have even ended up in trash because of my frustration at this stage.
How about sending unframed pastel paintings? Do you fix them for the customer and how do you protect them for shipping? If I don’t fix a painting done on sanded paper, how can I tell the buyer clearly enough to be very very careful with it and advise the framer to be careful, too?
