Since posting My tutorial on how to add a pastel background to your picture I have received a number of questions asking if certain other media, such as watercolour pencils and markers are suitable to use over the fixative. I didn’t know how to answer this as I have never tried. A review of the internet failed to turn up any information so there was nothing for it but to give it a go myself. And, while I was at it, I may as well video the whole thing so people could so my process. I chose to test water based markers (using my Tombow markers), watercolour pencils and Derwent Inktense pencils. Check out the video below for the results.
