Which cake specifically?
AThe top tier of the royal vintage wedding cake. I looked for hours and found pics of her classes and you can tell its a pattern that they transfer but I just can't find it or anything similar.
AHeres an up close pic. of what I'm looking for https://mbasic.facebook.com/photo.php?fbid=10151220547772347&id=75392687346&set=a.10151220546832347.475367.75392687346&source=49&refid=17
AIt looks like a piped pattern, it could have been inspiration from a dress, some floral lace, just some free hand flowers and leaves.
You could always ask her, she has a blog. I think you'd have better luck making your own pattern with parchment if you don't feel comfortable doing it freehand.
Ah...ok...I was sure you meant the awesome giraffe cake...I was going to direct you to a tutorial...
