Ivory buttercream over red velvet cake. I used a 2D tip instead of 1M tip on the roses so the petals would be a bit more defined, since I was using Antique Silk sparkle petal dust in spots all over the cake to add dimension. I'm now a huge fan of using the 2D tip on these roses instead of the 1M! The roses just seem crisper, and you have less "duds" that you have to scrape off and do over to keep from just looking like a spiral.
