Making a hat on circular needles. Is it possible to make cables? I hate sewing up and it would make it so much easier.
Sure! There are lots of cabled hat patterns. If you look in What’cha Knittin’ at the thread called FO - Lotsa Hats you can see one I did with several posts where I talked about it.
Cables are even easier in the round. You can cross them easily on any row you’d like and you always see the right side of things so you can easily see how things are going.
As a matter of fact. I finished this hat, http://www.knittinghelp.com/forum/showthread.php?t=28329 from here at knitting help and it uses cables in the round.
