Can you..... Really?!?

i am going to knit a blanket using the proper needles for the yarn i have chosen. My question is can i knit on enough stitches using 14" needles for a 60" blanket? Or must i do it in parts?

14" needles will be too short. A better way would be to get a circular needle and use it like flat needles. I think a 40" circ should do, a longer one would allow you to spread out the stitches so you can see your work better.

Those are too short, but part of the problem is that it will gwt too heavy. A circular needle is the way to go. That way the weight can rest in your lap . I’d get a long cable, probably at least 40".
