I use the baby soft yarn, i think it's 3 ply on the smallest knifty knitter for preemie caps. If you use a regular yarn, or even a sport weight, the hats come out kinda stiff, and you definitely don't want them stiff if you're looking to make preemie caps.
I can get just about 3 caps out of a skein of the Caron baby yarn, double wrapping the pegs, and making the bauble for the top.
I use to largest size round for small blankets. I just go the whole way around and stop before I get to the overlap, then work in reverse the other way to make a blanket.
I have the straight knifty knitter, I'm not terribly pleased with the chunky weave it puts out for scarves, but it makes AWESOME blankets. You just have to make a few panels and sew them together or crochet them together.
I wish I'd taken a picture of the last box of preemie and chemo caps I made to take up to Children's. Remember, if you're into making preemie and chemo caps, the softer the yarn, the better.
I'm going to be at my
Wal-mart tomorrow. I'll have to see if they're clearancing them here.
