Donald Robertson is the hardest-working genius in fashion. By day he's Head of Creative Development for Bobbi Brown. By night he uses paints, sharpies and duct tape to create a never-ending stream of artwork. His instagram feed is a must-view destination for style addicts worldwide and he's now launching his first book: Fashion Is Nuts, a 40-page collection of portraits of Robertson's favorite iconic faces of fashion painted on walnuts. Yes, walnuts. The book is printed in a limited run of 1000 copies, so shake your butts (and your walnuts) out to get a copy (you can find them HERE) before they're sold out. We chatted with Robertson to get the scoop.

What makes a person good to be drawn on a nut? Can someone with any shaped head be a nut or do they need certain types of features?
The person has to be slightly nuts, that's all.

Do you remember the first fashion person you were really interested in or inspired by?
Yes, everyone on the Jackson 5ive -- it was their Saturday morning cartoon. It's burned into my brain and my work.  A highly recommended Google!

Do you think people are flattered to be made into a nut or has anyone been insulted?
Pat McGrath was the only one I was worried about because her skin is so smooth. I searched for the smoothest walnut I could find. She just flipgrammed the whole Fashion Is Nuts book to her hundreds of thousands of followers on Instagram yesterday. So I'm good. Ali, the manager at Sant Ambroeus showed Grace Coddington hers. She laughed, I'm told.

Is there ever a time you don't feel like working?
No. I'm a day and night laborer

Who are your portrait dream subjects?
I nailed them all in the book!
