I’ve started doing little oil painting studies in my sketchbook! They are loads of fun and help me work out which colours I’d like to use in my final paintings.
My sketchbook has standard drawing paper, so I coated the pages with several layers of gesso before applying the oils. Just to be sure the oils won’t seep through all the other pages.
Do you do studies before working on your final paintings?
