I've recently discovered the joys of knitting. What pleasure! So far, I've finished a scarf and a baby sweater. Now I'd like to knit a blanket for a friend's newborn. Since it'll be 24''X18" I've been advised to use circular needles, which I've never used before. I can't get my head around how you use circulars for a rectangular design. I understand how to use circulars to form tube designs, but a rectangle? What am I not getting here? Thanks a bunch.
Also, if anyone has knitted a simple pattern they particularly loved, please share.
