I do. Bubbles are one of the hardest things to paint. I remember that from art history class in undergrad. It's surprising how much I learned in that class. It was the most challenging class in college. It really was a history course and covered such a large expanse of time. It was the only A- I made in college; I had a 92 average and it took a 93 for a full A at my university.
Love them. They remind me of bubble baths as a kid, and those games one could play blowing diluted detergent through a ring - wondering at how they caught the air and travelled the up drafts, watching their wobbly floating, their mesmerising rainbow highlights, their fragility as they burst into "nothing" with a wet drip.
