this is a really cute idea!

Materials

Pair of ankle socks or peds (I am using lace peds from Uniqlo)

1yd of ribbon to match

Sewing thread to match ribbon

Scissors

Sewing machine

Directions

Step 1: Tie a practice bow in the ribbon, and play with the bow size so that it will be proportionate to the sock/ped.

Step 2: Cut the ribbon, leaving some extra length.

Step 3: Sew the ribbon to the socks/peds by sewing the center of the ribbon to the back center of the sock using a 1/2” straight stitch. Stitch the ribbon on lengthwise, because when the bow is tied, it will be horizontal. Don’t forget to backstitch at the beginning and end of your stitches to secure everything in place. (Note: Stitches in white for demonstration purposes.)

Step 4: Tie the bow and cut off the excess ribbon.
