SPA - Feeling Blue

I found a technique that I thought I'd try while hopping around blogs...and now I can't find the link to properly credit the artist!!! It's a gesso technique, using aluminum foil, salt and sugar...really you should use oranges and browns to give the rusty look, but I decided to go with the blues for the SPA challenge. The image is from Diva D'Este. There's plenty of texture with this technique, too. Thanks for stopping by!
