Help anyyone, where can I get a diamond design roller or template for a cake. I want to make a 2 1/2 in diamond design on a cake. thanks

LOL I'm buying one too. You get it from global sugar art its an imopression mat.

I got this one and her video on how to. Love it. http://sugaredproductions.com/Decorating_Supplies.php

I got mine at Earlene's cakes. She offers 3 different pattern widths. Here's the address:

I use a quilting wheel to trace the long side of a right triangle onto the ride of the cake in even intervals around the cake, then flip it and go the other way. With this method you can make the diamonds as small or large as you like without having to buy multiple impression mats or tools.
