After a frame has been given its first size coat of glue, (depending on the preferred methods) in can be painted with gesso, or it can be painted with another size coat which contains a small amount of whiting - a very thin gesso. The top photo shows me brushing a thin gesso mix onto this frame, working it really well into the wood grain. The second photo shows how this thin gesso has dried. Next the frame will be sprayed with gesso.
