I'm using this pattern from Lucy - it's really straightforward to follow, even for relative newbies like myself. I have only made one proper mistake so far, which is making my initial chain too tight. It's a problem that I'll just have to live with - it's not major - it just means that one edge looks a bit stretched as opposed to all the lovely bendy ripples!

I am super pleased with how it's going so far, even though it's a slow process; each row takes about an hour, so a single coloured stripe (2 rows) is two hours' work. A labour of love :)
