Boo Cat started as an example to students on how they can make a peel painting where you squish paint together and peel it apart to make these cool textures lines, but now not in abstract form. Now you can make a basic animal shape and keep the thicker paint contained in that shape, then do the press & peel technique.
Boo Cat was pressed with a paper on to canvas to reveal these neat downward strokes like fur, and then when you peel off, you have a mirror copy on both surfaces.
So how to make each an original & different? Well the paper copy was used to press on another canvas for a basic outline, and then more goops of thick paint was added with a fork to form the fur of "Textured Cat" a second painting from the first paint mix, but that looks totally different.
As the Eyeball Ebook was developed, showing different ways to use these acrylic 3D eyeballs Ruth worked 6 years to develop, this left a myriad of uses to put the eyeballs in. She teaches in her authored book "Artist's Block - The Myth" how there's no room for artist's block ever, and how one idea leads to another that gets you in the creative flow.
