boat neck vs crew

Because of the heighth of the boat neck neck, there should be more rows in the upper garment in the boat neck than in the crew.  Add 1"-2" of rows.

Also because of the k3p2 pattern in the boat neck -- at least with springy yarn and a size 7 needle--, continue adding stitches at the raglan seams until there are 10 stitches extra before starting the lower garment.
