It’s like toothpaste for your muse

There are a couple ways to charge up a toothbrush. You can dip it directly in a paint puddle, but it is hard to fill the bristles evenly with paint.

Here I charge the toothbrush from my #8 round brush. The advantage of doing it this way is that you can add as much paint as you need easily and in a controlled manner.

You don’t want the paint dripping from the toothbrush.
