I've been working on a really big project lately (it's for my book!) that is basically three long panels of knitting that will be sewn together to make a baby blanket. The panels aren't very wide -- just 12 inches -- but they end up being 36 inches long before you cast off.
For some reason I started working with a pair of straight needles, even though I'm sure at the time I knew that was lunacy. And sure enough, about half way through, maybe not even half way through, I couldn't take it any more. The weight of the project was hurting my hands, and I had to take frequent breaks.
It wasn't any fun at all, but I knew there was a simple solution: changing to a circular needle.
Using circular needles to knit flat is a great way to take some stress off your body, to take up less space when you knit while you're traveling, and to help ensure the stitches stay on your needles when you put your knitting away.
I love using circular needles for a lot of knitting projects and really don't know why I didn't just start with one, other than that the straight needles were handy.
Do you use circular needles to knit flat? I'd love to hear more about your experience with them.
