I'm only a couple of years late, but finally took the plunge and started my first Clapotis. The pattern seems like it will be fun, but I made a major error before I even began my project.
The yarn is Lorna's Laces Shepherd Sport in the Shadow colorway. Love the yarn, just not for Clapotis. There is way too much contrast and the stripes are not so good. The odd green color in the photo is not accurate--the colors are white, black and grey. What was I thinking? Serves me right for buying online, I guess. This yarn will be frogged and probably put up for sale on eBay. I got 4 hanks and don't really want to knit 4 socks just alike. In sock-size scale, the colors would probably look great. I have ordered a new colorway and will post my progress.
On a related note, remember a couple of days ago that I mentioned Squidoo and the lenses I had started? I was feeling inspired and decided to start a new Clapotis lens. I figure it's a good way to gather together as many tips as possible while I work along on my version. Too bad I missed the hints about color choices.
