Take your time when working with minerals. You will soon find an application method that works great for you. You'll appreciate the evenness of the color, and concentration that the powder allows for light or heavy coverage.
Always remember: A little goes a long ways!!!
Pour out a small amount of the minerals into the lid of the foundation jar. Swirl the brush in the jar, most of the minerals should disappear and be consumed by the brush. Tap the brush against the rim to set the minerals in the brush. This also should knock off any excess minerals on the outside of the brush. You do not want to have the minerals visible on the outside perimeter of the brush.
Tip: To set the minerals even further into the brush; tap the brush vertically one the end of the handle so the minerals will go straight down into the bristles. This method may require more buffing, but is helpful in situations where coverage is thick or un-even.
