I have an order for an all buttercream wedding cake, and I'm getting nervous! here is the inspiration cake: http://www.brides.com/wedding-ideas/wedding-cakes/gallery/cakes/editors-pick/detail/186811?docPos=45&real-weddings=real-weddings
She wants the same design idea but on a round cake. I'm stuck on how to produce the vertical stripes on the middle tier. any suggestions?

TIA!

I think the stripes were made using an impression mat. I've seen one before, but need some time to figure out where

Here's one: http://www.cakesbysam.com/store/cart.php?target=product&product_id=21527&category_id=289.
