What tip do you use..??? How do you know which way to go with it.. Sorry if dumn question.. They teach us how to do this in class.

I normally use tip#2 and make "R" and "S" shapes, making sure the lines do not touch. Start and stop at the edges of the design so you can cover the ends with a border of some sort.

Hi If you want a fine delicate lace use a supatube PME #1 tip and use royal icing. It's beautiful. Key: Just make curvey not straight lines and keep as close as possible without letting them touch.

Thanks... Guess the icing has to b pretty thin..

not really thin, i did it with my regular bc with a touch more milk. piped just fine do some doodles on paper to get used to just going with the flow in all sorts of directions.

The tinier the tip, the more delicate the cornelli is. I also use the #1 - think s's, c's - just don't overlap - it is a beautiful effect when done correctly!

be sure to use a #1 tip.. s's and r's. and keep close together... if it is on a buttercream cake i use buttercream... if on a fondant cake.. i use royal icing.... just make it look delicate...
