I am knitting a sweater, my pattern says to knit across 15 stitches, slip 6 onto a holder which I have done, the next part says to join a second ball of yarn and knit across remaining stitches. Working both sides at once with separate balls of yarn bind off 2 sts at each neck edge.
I am not sure how to join the second ball of yarn and what the rest means.
Can anyone help???
