Thank you, Pete, Chris and Ken!
Chris, it's best if you grind the pastel stick on a fine cheese grater (don't tell my wife) and use an eye shadow applicator to apply it (I bought my own-embarassing). Use light, even strokes on a matt finish to get the desired effect, brush off the excess, remove the masking tape, then smooth it out with a cotton swab or bud, depending on what part of the world you're in.
Ken, I'd love to see you build one of these. I know you'd do a masterful job.
Cheers,
Bud
