Yes I did at the time Nancy. It was an art class so we worked with acrylics on cardboard but I have to confess it was about 10 years ago and I'm not sure where it is now.
I used birds, feathers, blues/mauves - flowing lines representing movement - light and airy. (I feel very peaceful when watching the lovely lines of my birds flying.)
Some used more dramatic colour cominations representing their inner turmoil, others suns/moons and night skies or mystical things.
It was rather revealing and in some cases somewhat confronting and certainly gave food for thought. I could see it used as ongoing therapy to work through emotional issues.
I think just the design process and the repetition of the design has a calming effect.
