two needle baby sweater advice
I am new to knitting and just starting on my second baby sweater: the famous zimmerman baby sweater on two needles. I've seen others ask this same question, but wasn't able to locate a response...if someone can offer advice or point me in the right direction i'd really appreciate it!
This is sort of a 2 part question. The directions state that after about 16 rows of garter stitch to switch to the pattern. Then is says "At 4.5", work 25 sts, then work back-and-forth on the next 28 sts (plus 7 sts cast on at each end of them; 42 sts in all) for about 4" sleeve."
1: what does she mean by 'work back and forth' ?
2: how are these directions different if i follow the advice of many bloggers that suggest doing seemless sleeves with circular needles?
