This isn't a book, it's an art manual. But it's not a guide on how to make art. It's a guide on how to make a mess.
I bought this because I hate making mistakes and thought the exercises might help me let go of my perfectionism, that fear that I might ruin something by adding too much to it or working on it too long. I didn't want to learn what happened if you buried a book in the ground for three days and then dug it up, or put something moldy inside it, or dipped it into some Jell-O. I can live without knowing that. So I skipped the prompts that would inevitably lead to mold, and the ones that required outside resources like cameras or friends, and the physical ones that wanted you to do everything with your non-dominant hand for a day or "lose your balance and attempt to record it in some way" as my life is already physically challenging enough as it is without adding extra difficulty, thanks. But I learned I like gluing things to other things, which makes sense given my interest in collage, and that oil pastels over Sharpie looks pretty awesome, which I never would have tried on my own, and that I hate strangers telling me what to do, which I already knew.
Keri Smith has a number of books in this vein. Check them out if you're looking for someone to tell you it's okay to make a mess, or a mistake, or just need permission to experiment, to use your art supplies in ways that you might otherwise consider wasteful, except now it's part of a learning process so it's okay.
My favorite two experiments—and outcomes—were:
1. Painting a page with Elmer's glue and then pressing a bunch of shredded paper (from the paper shredder) into it and then slamming the book closed.
2. Covering a page with gesso and then sprinkling the contents of my pencil sharpener over it—except I'd picked out the wood, leaving only the shavings of the colored cores from my colored pencils. It's bright and cheerful, and on the facing page, the core shavings leave little squiggles of color.
This is about experiments and mixing media and not worrying about the outcome being good, or interesting, or attractive, or even successful. If you've made a mess, you've done your job. If you've learned something in the process, even better.
