Working on some Birds right now for my June 2013 class.  I'm using heavy watercolor paper and Twinkling H2O's again.  My thinking is that doing watercolors in my class 2 months in a role will help the ladies to really get in the watercolor mode.  I love using my Copics but sometimes I get in a little rut.
July I might even do the Tombow watercolor technique.
Watercolors can be done with pretty much any water-based inks or paints (I sometimes use re-inkers or even pads as well).
My husband and grandson are out mowing and weed-eating right now making it a perfect time to create so, I'm off and back to it!
