Wilton designs. I used a #2 tip for the cornelli lace, should have used a #1. But, didn't use a coupler. :-( These were the only two I did with the lace design. Just wanted to try it without making too much more work (new icing bags and cramping of the hand, LOL). They were for family parties. Of course no one else noticed except me. NFSC with antonia's icing.
