circular sweater pattern help

[raeann97]

Hi-
I am working on a circular sweater pattern from www.morehousefarm.com it is a tunic and it is my first sweater. I am a little confused by the directions. This is the part I am confused about:


Divide for armhole: knit 60 (66/72/81) stitches—half the number of stitches of tunic—then turn and purl back (on wrong side) to beginning of round. Continue working back and forth on front half for 44 (46/50/54) rows. Always knit first and last stitch, even on purl rows—it will make picking up stitches easier around sleeve opening later. Measure about 2 1/2 yards of yarn for binding off shoulder and front neckline (you'll be binding off shoulders from front and back together), then break off yarn. Work second half of stitches for back of tunic to same length as front. Now bind off shoulders using three-needle bind off. Bind off 20 (22/25/29) stitches from left shoulder toward neck, then bind off same number of stitches from right shoulder toward neck. Then bind oft stitches around neckline—pick up (and bind off) one extra stitch at each shoulder where front and back shoulders join. Bind off stitches around neckline loosely so that head fits through neck opening comfortably.

I understand how to knit the first part of the stitches, knit and purl then cut my yarn. But how do you attach my yarn to work the back? Also, when I do my three-needles bind-off where is the third needle coming from?

Thanks in advance for your help!
