This particular variation of Julia’s 3-D Christmas cookie box is lavished with oversized poinsettia cookies decorated with the wet-on-wet marbling technique. And that’s not all! The personalized inset window is stenciled two ways – both with airbrush coloring and royal icing. For all of the project details, see Julia’s two videos: first, this one, which covers the making of the box bottom, and then this one, which addresses lids of different styles.
