I didn't quite nail the look I was going for today, but it turned out okay anyway.
I used almost all acrylic paint for my frosted sugar cookies, save for SOPI I Come in Peas as the green, and Rica Blackout as the base.
I used gold nail vinyls (I believe from Twinkled T but they're so old I can't remember for sure and haven't been able to find them in any vinyl shops I can recall purchasing from), but they kept tearing and were too sticky no matter what I did so they kept destroying my polish! I got fed up and decided to just lay them over a black base and use them as my "cookies" since they were a close enough color to sugar cookie dough. Overall not my favorite, but they still turned out cute!
