Thanks! Actuall, they were pretty fast. The rolled buttercream covers the whole cookie. The heart-shaped cookies just have dots on them, then a pink dot on the V of the heart, and few dots to make the pearls. They were pretty simple. The dress was also just dots to make the dress, and the sash was created with a flattened "snake" then outlining the bottom and the sleeves.
I put a little shimmer dust on the hearts, too. They actually were pretty simple to decorate. I borrowed the idea from cookies I saw on this site, so I can't take any credit for creativity.
