I purchased a jar of Daniel Smith watercolor ground in titanium white and buff titanium. I brushed buff titanium on a gessoed baltic birch panel then sanded it. The brush strokes still show on this one. Maybe putting another coat on will fix this. The ground does a good job of handling the paint, The main problem with this one is I applied the ground over a gessoed board which resisted the watercolor. White gouache mixed with a little ultramarine blue was used on the sky. The rest was transparent watercolor. I washed this off leaving faint images that can now be painted over with another coat of the watercolor ground.
