adding a shawl collar on a sweater
After sewing the shoulder seams, I'm adding the shawl collar to a kids sweater. The pattern says with circular needles, pickup 33 stitches on the right side of the front neck, then cast on 37 stitches and then pick up 33 stiches on the left side of the neck. Then the first rib row is P1(0:1:0),k1,p1 36 times. It says this row sets the rib.
I don't know what P1(0:1:0) means. Also don't know why all the first pickup stitches aren't being used and don't know why the back of the neck is is not being joined (it says cast on vs pick up stitches.
Then starting with the 2nd rib row, it says rib 43, turn, 3rd is rib 46 turn and it keeps increasing by 3 stitches. Where are the extra stitches coming from?
