The pieces of the frog doll are now ready to paint. On the last paper clay piece I worked on - the two ducks and the beggar frog - I gessoed the paper clay before I painted it. The painted surface turned out a bit rough and I figure there were two possible causes for that. One is that I didn't sand it with a fine enough grit sandpaper. I think I didn't go beyond 220. But the other possibility is that the moisture in the gesso may have slightly softened - and roughened - the surface of the dry paper clay.
So this time I made a couple of changes. First, I sanded with 220 grit, then 400 grit, and finally 600 grit. When I was done sanding it was quite smooth and I wanted to keep it that way. So instead of using gesso as an undercoat for the painting I used Krylon spray Workable Fixatif. Once the fixative was dry, the surface was still very smooth. So I've got quite a nice base for the painting.
The thing I liked so much about the gesso was that it was such a nice surface to paint on. Floating was a dream! We'll just have to see how it goes on this surface.
