Thanks for the feedback!
Ahh that dreaded lip is all I see when I look at the photo too! hehe! It was ganache under fondant - I was rushing to get it done and didn't have my ganache smoothed and finished properly. So annoyed at myself that I didn't take the time to really do it properly!
Thank you for the links though - I haven't used much buttercream at all so I'm sure they'll be very helpful when I tackle it!
I was terrified of the ruffle technique - it came about purely because I was wanting to see if I could do it or not and had a trial on a dummy cake, posted the results, and my girlfriend said that is what she wanted for her engagement cake =] The ruffle layer in that cake is actually a dummy cause I wasn't confident I'd be able to replicate it on an actual cake - so it's the top and bottom tiers that are edible and the middle ruffle is a dummy =]
