Hi! New to this site, intermediate knitter (sort of!). Am finishing a bolero type sweater knitted in ribs. The hem is g stitch (6 stitches). As I am assembling the hem, I'm wondering if there is a way to assemble this hem in a "stretch" way. The way I'm doing it now, back stitch, the stretch in the ribs stops at the assembled hem. I find this frustrating and am wondering if there is a way to make the hem stitch stretch also. Am giving this as a Christmas gift, leaving on Dec 20. Thank you so much to anyone who can help me!
