Can I repeat what I said in my earlier post try using the Pen Tool. Don't worry at all about trying to be accurate just get the rough shape down and then use the Direct Selection Tool on each node. The Pen Tool is what gives Illy its power and strength and all that is required is a bit of practice and if you select the correct brush you have have the most wonderful swirls. Here is a video showing a different way of doing swirls which might help: http://www.youtube.com/watch?v=WKWgtn_axTY
