What do you do when you run out of Gesso?
Make your own!
2 parts PVA glue
1 to 2 parts pigment. (I use either black or white acrylic paint)
2 parts talcum powder. (Baby talc works too)
1 to 2 parts water. Use enough to create the consisteny you need.
Mix everything together. Keep mixing until it’s smooth. Use a container that you don’t need to re-use for food.
