This is a club technique card using Epsom salts. I know what you're thinking. lol But isn't it cool? Dissolve 1 cup of Epsom salts in 1 cup of boiling water. Paint on cardstock with a paint brush. Ta da! Be very sure your containers and brushes are clean before you use them, otherwise, the technique may not work. I love the Frosted Window look, and it was extremely easy to do!
