What are the exact lace molds on this cake called? And where can I find/buy them?

There's all kinds of places selling lace molds.  But I'm not sure we can advertise them on this site.  Google Sugar Lace Molds or Fondant Lace Molds and have a blast looking.

Try Jennifer Dontz site Sugar Delites.com.   Hunt through her lace mold section.  She should have them

I don't think it's advertising if you aren't personally selling and profiting from the item.  Hmmmm. Who knows.

AYes you can post links to where to buy them.

Thanks everyone! I found them on Sugar Craft.
