Hi Suzeeq, I actually always cast off the same. I use the knit one, knit another, slip the first over and off technique. Any describes it on her site here. It's the only technique I've really ever used. I tried a purl variation once and didn't like the look. But I always obtain a flare in doing the knit cast off.
Hi again contiknitter Like rissa I'd need a link but the fact I'm 3/4 way through item now means in this case I can't vary cast on. Just work to get the cast off right! I'm using Paris Mohair by the way (if anyone knows the yarn) and as it will be a very long edge (for me about 120cm) doing it badly will be noticeable. On small items like scarves often the fringe will pull it in but this won't have that..
Just out of interest, the thumb method of casting on I see from time to time in a pattern. I never knew how to do it until I saw Amy's video but this is quite easy. Is there some advantage in doing this? (Sorry, I will get used to using the right forum for general questions)
