I've been thinking about making another pair of socks. I really like the Basic Sock pattern from I Can't Believe I'm Knitting Socks, and it seems like now is a good time to talk about knitting on double pointed needles.
Here is a video to show you what knitting with double pointed needles looks like!
I know that tutorial is for when you switch from circular knitting needles to double pointed ones, and that's a little different from when you knit on double pointed needles from start to finish. Actually, no. It's pretty much the same. It may not feel like it when you get started, but it is. Knitting in the round is moving your stitches around and around.
Knitting in the round on double pointed needles is moving your stitches around and around, and from needle to needle. I promise that it's not a big deal. When you're knitting a hat and move to double pointed needles because you've decreased to the point where you have too few stitches to knit on a circular needle, you'll probably divide your stitches onto three needles. I'm not sure why, but that's just how it works out with your stitches and decrease points. Your pattern will probably tell you.
I think I prefer to knit on four needles, just because. I found out that I have an easier time hanging on to four than three. Maybe I just like it because it makes a square. In fact, I like it so much that I'd tell you that if your hat pattern doesn't specifically say "You need to divide your stitches evenly over three needles," then you should divide them evenly over four needles. You just should.
You should try all kinds of things. If you haven't knitted with double pointed needles before, a baby hat might be the best starter project. Or you should just throw yourself into sock knitting with wild abandon because there's no reason not to! Have fun!
