A You Tube video by CeeCee showed her doing this warm up exercise using watercolors and a permanent ink pen. I made a couple samples and posted the link to our group so they could be inspired and know what to expect.
After our show and tell and sharing time, we settled into doing our own versions of CeeCee's exercise. We are usually very chatty, but everyone got so involved with this project, you could hear a pin drop.
Here are some of mine.
