Well I bought a sheet of masonite from Lowe's and cut it up into 6x6" inch squares. You can get a lot of panels out of a 4x8'! Next I applied three coats of gesso, let it dry, and I was ready to go. I've painted on gessoed panels before but found myself a bit frustrated with how the paint handled. It felt good this time around though. I love limes. Ever squeeze em' into Diet Coke? YUM.
