I am new to the forum. I am making two wedding cakes in the next two months. I am making a vintage cake and i would like to know whether i should paint on the lace or try to make it out of fondant. But my bigger question is how do i get the fondant quilting to look puffy? I don't even know where to begin on how to make the diamond shape or how to make it puff out. Please help.

This was my first attemp at quilting:

It was on a dummy for a wedding show, so it is not as "puffy" as it would have been on a real cake. I used a triple diamond cutter and was surprised at how easy it was. I went back and added some more detail after the cutter and was pleased with the result.

I just saw this over the weekend where they did a puffy quilt pattern over a box lid:

it kind of puffs automatically. the degree of puffiness is related to how deep the quilt/etch marks are.

angel thanks sooooooo much for posting that!

These are 2 that I did that are diamond. I didn't put anything under the fondant but buttercream. It just kind of puffs out like that when you make the marks.

i followed the link angelfood4 posted and it worked great for me

I find that when using the diamond quilting cutters if you have a thicker crumb coat under the fondant you can control the puffiness pretty easily. Just lightly push in the cutters just to have lines, or push them in further or go back over the lines with a stitching wheel and you will get a puffier effect.
