Cast off. Sew up back and bottom seams.

Tie - With a 4.00 mm crochet hook, ch 70.
(You could also use a ribbon.) Weave tie through 1st row of ribbing. It is easier to do if you leave the tail end of the yarn on one end of the tie. Use your crochet hook to grab the yarn and weave the tie through the ribbing. With a sewing or darning needle, weave in the tail ends of the tie. Tie into a bow in front of the slipper. Fold down cuff.
