Anyway ...
I ended up buying Loew-Cornell golden taklon ultra round brushes in size 2 and 8, and a Simply Simmons #4 fan brush. So far I'm very happy.
I already had Simply Simmons 14 mop (?I think), and a 3/4 flat from a previous watercolor class.
Thanks Sadie for reminding me to keep my watercolor brushes out of the acrylic paint!
Today my wet on wet wash was better ... so maybe I don't have a favorite yet! I tried Deepti's suggestion to tap a damp paper towel through a stencil. I had a hard time controlling how much water. Sometimes it seeped under the stencil, sometimes I didn't have enough to take away any paint.
Off to practice some more ...
Before I go ... does anyone have any tip for mixing paint? In the class, Deepti's paint is already mixed and ready to go. When I try to move paint to a mixing area and wet it, or mix it, it seems all of the paint ends up in my brush with hardly any left on the palette!
