There are a couple of options in the “Your Supply List” in the left-hand menu to other brushes. If you can’t find what you need via the links I’ve provided, try jerrysartarama.com or Michaels.com.

You can use what you have for now while you wait for your chisel blenders to arrive, or until you have time to visit an art store in the next couple of weeks for a fun and inspirational trip to see if you have something you’d like.
