A bride wants to incorporate their Scottish tartans in the design of their wedding & groom's cakes. For the wedding cake, she just want it as a ribbon around each tier. I think I can use a printed frosting sheet for that. But she wants the groom's cake to be a lab coat with the tartan tie. Since I haven't worked with printed frosting sheets before, I don't know if it will be flexible enough to form into a tie.
Any suggestions on ways to make the tartans would be appreciated.
