This was painted with the Langnickel royal sable 5520 #4. I used one brush almost on the entire painting. This brush was purchased years ago. They don't make the royal sable anymore. As soon as I laid down the last stroke, the hairs came out. It worked great before that.
Usually, I'll get the palette knife out to work some of the edges. For this painting, I chose not to. I did use a pallet knife for one thing.....the petal sitting beside the vase.
