All my school notebooks had doodles down the margins.
It wasn't that I was not paying attention; actually, I could remember what was being said by looking at the doodles.
I took notes too. I don't mean to say the doodles were the ONLY thing I did while in class.
Some doodles grew into pictures or expanded into design.
This little doodle is about 3 times larger than the original. I liked it so much I cut it out and glued it on a larger piece of paper so that I wouldn't loose it.
The first time I used this design was on a large slab of clay rolled out with the intention of cutting it up. But when I looked at the shape, I liked it so much I coaxed it into a large platter, smoothed the edges and fired it. The "Angry Cat" was done over the iron glaze with thinned oxide.
Every time I've used this design, I've sold the piece.
