One of the modules for Spectrum was on the word Activate. First we painted a intuitive style painting and then we ripped it up and used bits of it for collage.
This is the painting and I hated it, I was so happy to be able to tear it up. I should have just painted over it or something but I didn't. Ripping it up gave great satisfaction.
I used pieces from the painting as collage elements and then added more. Its a great way to use something you don't like. Just recycle it into more art.
