What is similar to oil on canvas but does not need weeks to dry and is easy to use?What type of paint is similar to oil on canvas to make an original Georgia O'keefe painting for a project?
If you have never painted with oils or acrylics, or watercolor or other water medium, I suggest doing a pastel on medium tooth pastel paper. If you MUST do a painting, try acrylics. But you can never create an original Georgia O. The very best you can do, likley, is an original painting based on a Georgia O. reproduction...unless you have access to an original G.O skull painting. Even so, your work cannot become an orginal G.O. painting. So be humble in your effort and self-forgiving in your failure. Try to place your expectation in proper perspective....you'll be happier with the results. The exercise should be appreciated for what it is...the outcome, at your point in development, is secondary if not irrelevant.What type of paint is similar to oil on canvas to make an original Georgia O'keefe painting for a project?
Acrylic on canvas. I've actually never worked with oil, but I hear acrylic is pretty similar. And it only takes about half an hour to an hour to dry.
