Yes, the ruffles are a bit of a nightmare to make. However, they do get easier with practice but they are very fiddly. I couldn't have done it without the double pointed cable needles and I knew that I'd need them because I made a sample first.
To kayeknit and mks22300: I too fell in love at first sight when I came across this pattern. I was a bit worried that it said "advanced beginner" (as some may recall) but was told that I'll get all the help that I need on this forum. So, I summoned up the courage and had a go.
