Joining right shoulder seam
Still going with the baby's sweater and have now made up the back, front and sleeves.
The next stage of the pattern is front shoulder band. The pattern says this -
Using back-stitch, join right shoulder seam. With right side facing, using 2.75mm Needles and M, knit up 17 sts evenly along left front shoulder edge.
Work 3 rows rib as for lower band of Back, beg with a 2nd row.
Not having knitted to a pattern before, I'm not sure what they are asking. I assume I stitch (using back-stitch), the front and back right shoulder seam together. After that, I'm a bit confused.
Any help would be great.
