I have used OPs in the past, but now I am really into colored pencils. I have a bunch of Caran d'Ache OPs left and am kind of sad about not using them. Anhoo, I have some acrylic paintings I have started that I really don't love to do detail on because it takes forever with acrylic and I am at a serious premium for art making time.

Can I put oil pastels over the acrylic without worrying about the painting falling apart some day? How would I seal the OPs on the top? These paintings are on stretched canvas.

Thanks for your help.

You can certainly put OPs on top of the acrylic, but there is no sure way to seal them. There has been much discussion about various ways to do this. OPs never dry so at some point they could always be damaged. I am in the camp of framing them under glass. Maybe others who have tried not using glass could give you some advise.
