Check out the Gallery page for fabric printing results.  Painting skies is a fine skill.  But you have to start somewhere and they did.   We lost shade in the back parking lot so we needed to move the actual painting into the classroom and took the boards out for the fabrics to dry.  They were dry in 15 minutes - the sun was very accommodating.  The next class will be in September.  We will be painting earth/land and water, as well as other special effects.
