Here are the two paintings I made in Misty Mawn's class called, "A White Out." Neither painting is done, but I wanted to show what I was able to complete during the 6-hour class (actually about 4 hours if you subtract all the demo time from the instructor). The centers of the flowers in the bottom photo are glass beads attached with white acrylic paint.
Here are photos of the instructor showing us how to make a gallon jar of Gel Medium disappear in about 5 minutes! No, seriously, she is showing her techniques for layering paper onto canvas, then ripping it to create texture for the background. She uses a a LOT of gel medium for this. Rumor has it she owns stock in Golden.
