I did manage to get three quick pieces done. These took about 15-20 minutes, if that, including the time for drying and techniques.
I used salt to get the foamy, misty look in this seascape study.
For this second one, I was showing my niece how to do some wet-in-wet techniques, deciding what I was doing after I'd let colors mingle on the page.
This last one was a lesson in how much difference the paper makes. I used Arches 300 lb for the first two, and this last was done on Strathmore Aquarius II, a much softer, less rough surface than the Arches. The color is less brilliant, and tends to blend more on the paper. I got a far different look than I first intended. One paper isn't necessarily better than the other--you just need to use different techniques. My study would have been better if I'd taken a different approach. As it was, it was good practice in knowing your paper.
