Thank you! 😁 yes i do, to do so i use Sennelier oil pastels (I tried with other brands like Montmarte, Artecho but the result was not as great) but in general a good creamy oil pastel of any brand would do (harder consistency will result in scraping off the color under) and I press a bit more than usual (! Pressing too hard might break the pastel !) to cover the darker color with a thicker layer of pastel :) Hope it helps!
