The hard part might be making that invisible.
That's what I was thinking. I just found this instructions for another sweather
Using smaller circ needle, with RS facing and beg at one shoulder, pick up and knit 33 [36, 40, 44, 50] down left neck edge; place marker to mark center st, k center st from safety pin; pick up and knit 33 [36, 40, 44, 50] up right neck edge; and pick up and knit 30 (32, 36, 40, 44) sts across back. 97[105, 117, 129, 145] sts
Place marker to show beg of rnd.
Next Round: Work neckband in (k2, p2) rib until 2 sts before center front marker, SSK, k1, k2tog, work to end in rib patt.
Rep this round until neckband is 1 inch wide.
BO all sts in rib pattern.
Do you think they might work? mmm.... I've never done this before
