Knit with 2 strands?
I'm a beginning knitter, and I have a pattern that tells me to knit with 2 strands (of the same colour). I've searched and searched, but I can't seem to find any information on how to do this. Do I alternate them? Do I twist them together and use them like one really thick strand? (And it would be pretty thick, I think, since I'm working with boucle) Is there something else I should do that I haven't figured out?
Also, how can I tell which side is the right side and which is the wrong side? I've knit headbands and scarves and hats and the like before, but always with my great-aunt's guidance and corrections, and she never explained the 'sides' to me.
