Almost done guys! You just need to attach the waistband to the sweater and you are reeeeady to go! Let's start :)
Sweater all versions
Take the two waistband pieces and with right sides together stitch the short ends.
Turn it right side out and fold it lengthwise, wrong sides together, so that the raw edges match. Place the waistband all around the bottom of the sweater, with right sides together, and pin matching the side seams.
If you are making version B, tie the bows first and sew a row of stitches at the bottom of the back so that both back pieces are now joined together. Stitch all around.
