This rib has a very easy stretch which makes it challenging to hem. We recommend pairing it with a more stable rib knit for cuffs and bands. See link below for some great options of 2x2 rib.
Other sewing tips: significantly reduce your presser foot pressure and increase your differential for best results when working with lightweight easy stretch fabrics.
