Top border is the huge duck's beak leaf tip--#366.
The bottom is too blury for my to see well, but I think may just be large shells upright with smaller shells in between.
I agree with BlakesCakes on the top border, you can see it pretty well on the middle tier on the right. The bottom border doesn't look like a border at all to me. It looks more like just large dots every couple of inches.
looks like something like the piping on the far right of this photo only elongated a bit and done on the edge of the cake......what do you think?
I think the top border looks like hearts made with a large round tip 1/2 on top 1/2 on the side and a swirl on the bottom like blakescakes says an e motion
I was thinking e-motion on the bottom, too. But I'm not familiar with c-motion, so I could be off base here.
Agree on the borders; what are you going to do about the swans?
I was thinking about something like these favors.
WOW! You all are amazing! Thanks so much for all the input. The cake is for next weekend so I am going to play this weekend with all the suggestions!
As for the swans...Global Sugar Art has them (believe it or not!) They have the hole for the support post to go through. I think I ordered 12 for around $6.00. Cheap!
Thanks again for the advice!
Glad we could help! (and it's amazing you found the swans.)
