I found these pre-mades on the GSA website, and am wondering if any of you have used them on round cakes? They're 5" long so it doesn't seem that I could use them on a round because there's no curve to them. Does anyone know of any other pre-mades that can be used for round?

I've practiced over and over piping RI lace pieces, and my darned hand shakes after about 10 minutes. Ugh. Thanks!!
