How to knit circularly

I do have a 40" needle. But I tried using a small 24" needle which I love so no loops in the way. However come to decreasing you can’t beat magic loop. I actually saw a video on using one loop for magic loop.

I don’t mind the loops, but I’ve been doing it for a long time and use flexible cables. Some people prefer single loop. I just wasn’t happy with it, but maybe you will like it.
