I bought a new cookie cutter: a rouge.
I used three colors: pink, white and black. The method was to outline and fload the cookie from the bottom, so first all blacks, then white and at last pink. I use a piping bag with a tip 2. I made thr outlining and flooding with the same icing. I left the cookies overnight to dry, then I drew details on the cookie. For the second outline on the cookie I use a piping bag with a tip 0. Before I drew, I check the consistency with a few strings on my worktop.
