Practice a simple jar ellipse and one leaning brush. A few bristle divisions and local overlap shadows add enough detail to explain the objects.
Start with an oval opening and curve the sides down to a smaller base ellipse. Keep the two ellipses at a similar angle.
Draw a long handle at an angle, hiding its lower part behind the front rim. Add the short ferrule and pointed bristle shape above it.
Use a few broad divisions in the bristles and two ferrule bands. Add a little gray inside the jar opening and beneath the ferrule.
A small thing to tryDraw the full brush lightly first, then hide the section behind the front rim to make the overlap convincing.
