You are Never Too Old
A happy childhood is never out of reach according to Tom Robbins. I have never read one of his novels; but this quip has been oft repeated.
One of the things I never did was fingerpaint. Maybe it was deemed too messy or too frivolous or too expensive. We did not have art until fourth grade and the messiest project was the one where we colored a piece of paper with our crayons, then painted it with black paint and scratched out a drawing as we removed some of the black paint.
Recently I thought I might try something new—making books. One of the projects was making paste paper. This is adult finger-painting.
The steps are simple. Start with paper–a fairly heavy paper. Wet it on both sides. Spread some paste (I used pre-mixed wall-paper paste) colored with acrylic paint( I bought a six pack of acrylic paint from Dick Blick for about $6 several years ago), then manipulate the paste/paint into designs.
I used a cut-up foam brush; the bottom of a thread cone; some sort of rubber grid from the grouting section of Home Depot and a scrubbie. The paper was ‘pastel’ paper.
I hung it to dry on my makeshift clothesline. 
Now I have a nice selection to use as book-covers or maybe even the pages of a hand-made book.
It has been fun learning a new craft–the terms, the forms, the artists. And a challenge to use what I have. I have no idea why I had pastel paper; I don’t recall ever working with pastels—but experimenting and learning new things is a happy childhood.
Here are closer-ups of the papers;
