Anyone know how this ruffle cake edge is done?

Thanks in advance!

looks like its done with a 1M tip

Definitely 1M

Thanks for the suggestion, I tried out the 1M tip the other day. I don't think it is the one that was used . The cake border in the link has a flatter looking ruffle. (hope that makes sense) I could not get the 1M to look exactly like it.
Any other guesses?

It's the wilton 2D tip. I used one on my son's birthday cake (w/ red buttercream) & his brother said it "looked like flames!"

Definitely the 2D tip--also makes a nice Rose when swirled from the inside out.

2D for sure.

...thanks so much. I'm going to try the 2D ruffle and the rose!

Erin is super sweet - you should PM her and ask what tip she used, I'm positive she'd tell you! She's here on CC or email her thru the TLB website.

I've done that with a 2D
