|'On A Grey Day' 16x20 pastel ©Karen Margulis SOLD|
It's back to class time! This week I started teaching my six week course at the Art School in Sandy Springs as well as my classes in my studio. I am excited to get back to a regular schedule after a busy holiday season. I had a great time this morning and I know I am going to enjoy my new group of students! They did great today! I invite you to follow along with the class. Each week I will report on what we did in class and share some of the tips I have covered. I hope you will enjoy and perhaps be inspired to try some of the techniques we will be working on.
This week we visit the underpainting and try an Oil Stain Underpainting.

I began class with a talk about pastels and papers and then moved on to a discussion of the underpainting. I then explained the oil stain process and started my demo. While my underpainting dried everyone worked on their underpainting. I then finished mine by adding the pastel. The top photo is my finished demo. By then all the underpaintings were dry and everyone finished. I was so impressed with the results. I wish we had more time for a show and tell session. We'll do that next week!
If you would like to try an underpainting with oils you might like to read a post I did on the process CLICK HERE Below are some tips to keep in mind:
- Use a sanded paper or a surface that can take a wet wash. I prefer Uart paper.
- You need to use a stiff inexpensive bristle brush. I like to use a large one. Sanded paper is hard on brushes!
- You need to use oderless mineral spirits such as Turpenoid or Gamsol.
- You need a few tubes of oil paint. You don't need a lot of colors. I use Alizarin Crimson, Cad Yellow Med and Ultramarine Blue. I don't use white or black. I mix a good variety of colors with just the 3 primaries.
- It takes practice to get the right consistency of paint...too thick and the tooth of the paper gets filled. Too soupy and you get a washed out underpainting with no good drips. Play around to get the feel it.
- Strive to let the dried underpainting suggest a direction for the painting. I try hard not to cover up all of the underpainting. I like the dribs to work for me.
