Hello All,
I am going to be Smooth Icing a cake with BC and I would like to do a diamond pattern with small flowers at each cross point (hope that makes sense). What is the best way to get a GOOD diamond pattern? I am afraid if I just try and eyeball it, then the lines will not be even or something. IDK any help will be appreciated!

You can use an impression mat to make the diamond pattern. I have used a brick impression mat before on a crusted BC icing, and it worked fine.

get the diameter of your cake use some wax or plain paper divide it into equally parts then wrap the paper around your cake again mark the spots with a tooth pick and then use a square to conect the dots. That's what i would do..haven't done it yet! good luck!

The best method I've found is to measure the cake, mark the top and bottom and then connect the top mark to the next bottom mark over using a thin knife blade or spatula. Then reverse and repeat to get the set of intersecting diagonals to create the diamond pattern. I've used mats and the diamond impression tool, but I've found that taking the extra time to mark and measure by hand always produces the best results.
