My sister in law is in love with the design on this cake and would like something similar on her wedding cake.  I believe these were all hand cut, but I'm wondering if anybody knows of any cutters or molds that will give a similar design.  I don't mind hand cutting them, but I'm afraid I want get it to look as clean as it does on this cake.  Thank you for all of your help and suggestions!

These could give a similar look:  http://www.sugaredproductions.com/shop/products.php?product=Filigree-Cutter-Set

Otherwise, they may have been cut with a Silhouette or Cricut.

Thank you so much for the suggestion FullHouse.  It looks like those cutters may work!
