This is fun! Mixing acrylics with water, trying to get just the right mix - not too thin, not too thick. Playing with colors 'does it need a bit more orange?' 'does it need less white?
Wetting the fabric so the paint will soak in easily and then going at it - brush in hand wildly spreading so there aren't too many sections of stiff paint. A wash is what I'm looking for so it means moving quickly over and over, sometimes just a touch sometime several layers.
"All that is necessary to paint well is to be sincere." - Maurice Denis
