There are many reasons why you would want to knit in the round. Knitting in the round is perfect for hats, sweaters, mittens, socks, etc. It also allows you to knit seamlessly, and thus, there will be no seaming at the end of your knit.
In order to knit in the round, you only need circular needles. The length of these needles will depend on what you are knitting. If you are knitting a hat, you would choose smaller circular needles. If you are knitting an adult sweater, you would choose longer circular needles. It can be difficult to keep lots of stitches on a small circular needle. However, if your garment is small, it might be impossible to join the round with longer circular needles.
The video shows you a few things to look out for while knitting in the round.
