Fold the cuff down. To create a hole for your thumb, cut a 1-inch horizontal slit through both layers of the sleeve, about 2 inches below the top of the cuff. Do this for both sleeves. Try them on to make sure the thumb hole is the right size and positioned correctly.
With the thumb holes facing the proper direction, decorate the tops of the gloves. Sew fabric scraps, and add embroidery floss and any other embellishments. Slip into your cozy creation and show off your handiwork.
