Thank you Laura, I've never heard of Zentagle 1. I will check it out!
One other thing I've tried is acrylic painting. I went to a 'Paint Nite' (in the afternoon) at a local coffee shop and had so much fun! There were about 20 others there painting the same thing with the instructor leading us. It was amazing to see that all 20 of us seemed to have a different interpretation of the instructors paint lessons. My painting turned out reasonably well, and I'd like to try another class. Now that it's gotten up into the 90s I may not get to go.
I'm sorry about your migranes, I hope you feel better soon.
