That is GREAT to know! Did you get to see them in person?
@elegant-one this is what she said about using 2 shades:
"Try applying the darker shade to your cheeks, edges of your forehead, and jawline blending down to the neck to add a bit of warmth and connecting your face to your body. And the lighter shade above/under your eye, center of your forehead, nose, and around your mouth/chin. Experiment with this and adjust for your own skin’s character. Enjoy"
I could not use #1 as my darker shade and #0 as my lighter this way because #1 is too yellow to be my main shade, but Maybe #2 and #0 would work based on what @Mac-Guy said.
