Knitting in the round with circular needles or double-pointed needles is the only way to make a seamless knitted tube, ideal for knitting socks, hats, even the bodies of sweaters.
When knitting small circular projects like socks and the tops of hats, most knitters learn to knit using multiple double-pointed needles. But another method of knitting in the round on a small scale that is popular with a lot of knitters is knitting with two circular needles.
Just the idea of knitting in the round with two circulars is enough to confuse many knitters, but it's really not that intimidating once you know how it's done.
The first step, as with any other kind of knitting, is to cast on the required number of stitches.
