Amazon.com: Cotton Square Braid Candle Wick - #1/0: Arts, Crafts & Sewing
That's the one I get. I use about 3 feet at a time and boil it to remove residue. Better to be safe. Be sure to not stretch it when wet as I've noticed that some of the thinner portions of the wick don't wick as well when it's been stretched. It puffs up nice N tight in the channels
Oh, and make sure your clone has 2mm wide ceramic channels. I'm not sure about 'em all , but I've heard they are different depending on which Ody they cloned. Mine are about 2mm wide. The cotton is just shy of 2mm when dry.
Dunno if you read this, but don't try to dry burn cotton... you'll just end up with ash. I get about 4-7 days out of my cotton wicks in this clone. I use the stack method where you put a shorter piece of wick over the longer piece and cut it where it's flush with the mouthpiece.. I have pics; i'll see if I can add 'em here.

I wouldn't put the wraps as far apart as I did in those pics. They look nice, but they're not as efficient as when closer together.
I've gone without using non-resistance wire in the beginning and is doable, but you lose a lot of heat. Here's a video that does a decent job explaining how to make the coil with NR wire and install it in the Ody:

He gets to making the coil at about 6:20 Hope this helps
