you can also knit a long staight band and then sew the cast on edge to the bind off edge.
(to make that more advanced, you can do a provisional cast on, work all the way and then do a grafting with kitchener stitch /3needle bind off to join seamlessly.)
Since I do not know where your knitting abilities are at, I do not know if you will do the easy or the more advanced part. The change is only in cast on and the bind off (replacing that by kitchener stitch or 3needle bind off). So if you want to be adventuros: dive right in.
If you do garter stitch or any other stitch for the length of the knitting...
Another - more advanced thing to do: A Moebius band, there are several instructions out there how to knit one. But that requires some daring on new techniques (still just knits and purls, but a bit more challenging on the cast on and so on).
Anyways: all these you can work either on straight needels or circs (I do only use circs, never straight needles).
