Here are the brushes I use.
I have four brushes that I regularly use. The first is my 'white' brush. I only ever use this tiny little brush to put on my white highlight shadow, I really like how the small square brush head smooths out the pigments and can really spread it as thin or thick as I want. The second brush is my most used brush, this brush is a medium sized brush with a fanned end. I use it for applying the pigments over my entire eye, including lining along the bottom portion of my eye if I'm doing that for a look. The third huge brush there is my blending brush, I use it for pulling out the shadow, usually right above the crease. The fourth brush there I only use for my eyebrows, I haven't found many other uses for it yet.
