Hi! Welcome to knitting help! You will find some patterns like hats and such you can knit flat. If you can, the pattern will tell you, and you just sew it up when you're done. For the most part though, hats and mittens and such will be knit in the round. For someone who is still new to knitting, I would recommend starting with a hat if you are wanting to start knitting in the round. The reason I say this is bc getting used to knitting with circular needles and dpns can be a bit tricky. I haven't even tried anything like mittens or socks yet, and I've been knitting for about 9 years now. But then again, I didn't really get the hang of the purl stitch til about a week ago either! lol. But anyway, I hope that my advice has helped you a little. And of course, if you have any questions, feel free to ask us on here!!! Good luck!!!
