This charcoal under-drawing was done on artist loft canvas panel, nothing too expensive. In fact, I recommend cheap canvas panels for beginners. Please don’t spend a lot of money on your substrate if you are just starting oil painting. You are going to making plenty of mistakes and throwing away (hopefully reusing if you can) plenty of studies.

I am using Dura-lar film matte surface as my substrate. It has just enough tooth to hold the graphite. It is difficult to get rich dark marks with pencils, however you can use other media to achieve that. This leads into why I love using this substrate. You can use multiple wet and dry media on the surface, like oils, gesso, and acrylics. I have not tried pastels, but I don’t see why it wouldn’t work. I look forward to experiment more with this surface and sharing my results.
