That looks to me like fondant pieces made with a lace press, and maybe some royal icing over piping?Then painted with luster dust mixed with alcohol (vodka or ever clear).
ALuster dust will give you that gold effect
Is there a certain brand of luster dust? I've tried a couple and haven't gotten the right color...do you have a good brand?
Hey! I would recommend a gold HIGHLIGHTER rather than a luster dust. A highlighter is going to give you a true gold. I would probably mix 2/3 Highlighter with 1/3 Kings Gold Luster to give you that color. You can find them online. We sell them on our online store. They currently aren't shown as available under a tab but if you search luster or highlighter they will come up. The website is market.megansbakeshop.com you could also get there by going to megansbakeshop.com
