Q: “Loved your flower painting; what size and type brush did you use for the petals? –M.W.”
A: It’s a large, flat, coarse, hog hair one that’s about two inches wide. They’re sometimes called a varnishing brush.
Here’s a short video clip to give you an idea of what I’m doing. Working wet-on-wet, remember is to wipe the brush regularly so you can pick up and apply ‘clean colour’. Remember too that whether the brushstroke is into the yellow or coming out of it influences how mixed the white becomes. Don’t second guess yourself but keep going. Mistakes can be rectified and overpainted later. She who hesitates is lost and all that.
