As many of you know, this month's theme is "Can't Resist This". So I thought I would share one of my favorite techniques that makes use of a resist. In this case the resist is gesso, but you could use any kind of acrylic medium.
First I coat the sketchbook page or paper with a thin coat of gesso and let it dry thoroughly. Then I fill the page with acrylic color, in this case some reds, golds and purples. While the paint is still a bit wet I spritz on some water from a squirt bottle, and tip the page to get some drips. Let it dry a bit more (the water is still wet!), then blot with a paper towel. If I don't gesso the paper first, then it absorbs the paint more and you don't get the dramatic effect.
For a second kind of resist, I cut out a shape (in this case, a bird) in freezer paper and ironed it to the painted page. I learned this technique from one of our sketchbook challenge participants, Laura, who posts on our flickr site. Then, I painted around the freezer paper mask before removing it. Just a sketchbook page, not a finished piece.
Laura said she got the idea from a tutorial on the Sew Daily newsletter, in which they were making freezer paper stencils for quilts. Click here to view the article (Thanks, Laura, for the link!).
