In the last post, we looked at using acrylic paint as an underpainting layer for an oil pastel piece. This time, we’re going to look at a medium that is probably not commonly used for underpainting: Gelatos®.
Faber-Castell’s Gelatos are a stick pigment often used for art journaling. They aren’t pastels, but they do resemble softer oil pastels in their consistency—but they are much more “mushy” and are in fact often compared with lipstick in texture. There are several sets of Gelatos available; for this piece, the pastel color set was used to match the subject: a retro Peaches n’ Cream Barbie.
Gelatos offer a lot of flexibility. They can be used dry (and blend into the paper easily) or can be used with water. Once they’re dry, they don’t budge—which makes them great as an underpainting layer if you want it to stay put. Also, you can draw pencil marks on top of it, and nothing will smear from erasures.
Gelatos aren’t noted to work well on canvas (from my research), so a mixed media paper was used. Mixed media paper also seems to work well with oil pastels, similar to bristol board, in that it offers a smooth surface for blending.

- Sennelier and Faber-Castell Oil Pastels
- Conte Crayon (for fine details)
Unfortunately, I forgot to take a photo of the underpainting layer. It looked similar to the underpainting done in acrylic paint but was obviously done in pastel colors.
All Pros—and No Cons
The Gelatos made a perfect underpainting layer for the oil pastel! They were applied dry and blended in large areas with a baby wipe; small areas were blended with Q-Tips. At a certain point, it was obvious that the outline of the nose was not drawn in (which I meant to do), so I went in with colored pencil to draw on top of the Gelatos. Even though some mistakes needed to be erased, the Gelatos did not move.
The conte crayon used for finer detail did well when used on top of all the mediums underneath when Gelatos were the underpainting.
So the verdict is in! Gelatos are great as an underpainting layer under oil pastels. They’re fun to work with, and are readily available at places like Hobby Lobby and Michaels—plus, you can use coupons there. I will definitely be purchasing more Gelatos for future projects.
