We get lots of questions about gesso. Gesso is a primer that helps prepare the canvas for painting. Our MBN canvases are already pre-treated, so gesso isn't necessary. However, if you do wish to use it, be sure it is clear gesso! We have had customers use the white gesso and cover all of the lines and numbers on the canvas. This is definitely NOT recommended if you are planning on having a relaxing painting session.
Each brand is different, so be sure to read the directions carefully on the bottle. Ensure that the gesso is fully dried before moving on to painting.
