Steps:
1. Get your mixing medium. If it’s stored in a bottle or jar, pour a dot of it onto a surface, like the lid of a jar. We don’t want to dip or double-dip our brush into the whole thing and contaminate all of the contents. For this tutorial, I used plain old water stored in a spray bottle. If your mixing medium has a spray dispenser, spritz a small amount on the back of your hand.
