Watercolor is the MOST difficult medium I have ever tried. With acrylics or oils I can paint away like mad and if I don't like it, paint over it. There is some correction possible with watercolor, but it is kind of an of -the-moment medium.
I am making myself vulnerable here and sharing my very baby student attempts at understanding the medium.
My paints are cheap ones. I want to mix my own paints using powdered pigments like Carol of Paris Breakfasts does. Check out her blog archives for August with a # of watercolor posts. Here are two other watercolorists I admire. Mary. Scroll down to catagories and click on watercolor. Irisz.
As the year continues I'll keep you updated on my watercolor progress or lack thereof.
