Great thread! I'm always looking for new border ideas. And having very little experience, I'm looking for easy borders. Someone mentioned looking for a more masculine border. I used a plain round tip to do this one for DH's birthday cake. He INSISTS on Duncan Hines canned chocolate frosting, which is VERY soft, so design choices are limited.
I did this cake Sunday with cream cheese frosting, again very soft. I can't do reverse shells, either, so I just did some S-scrolls. I noticed that I when I finished each one, the end stood straight up. I think I could take advantage of this "flaw" and, using some bright colors, come up with a very whimsical border.
Both of these cakes are in the gallery.
Thank you everyone for sharing. Many of these borders (like the frilly border on the poodle cake and the stringwork) are absolutely AMAZING!
