<b>Tape and Begin</b> Cut two 50" (1270mm) T-shirt yarn strips for each pair of flip-flops. Apply double-sided tape to the tops of the flip-flop straps. (At this point, peel off the backing just a little bit at the base of the flip-flop where the back strap is attached; this will make it easier to remove completely in the next step.) Starting at one side, add a drop of glue and insert the end of one yarn strip into the base of the flip-flop where the back strap is attached. Be sure to push it in deeply and securely.
<b>Wrap the Straps</b> Remove the rest of the backing from the tape and start wrapping the yarn strip around the flip-flop strap, pressing the yarn strip into the tape as you wrap. Continue wrapping until you reach the base of the flip-flop strap on the opposite side. Trim the strip, leaving enough to add a drop of glue and insert securely into the base of the strap.
<b>Finish</b> Use glue to add a single strip of yarn to the outer rim of the flip-flop. Alternatively, cover the entire rim using three rows of yarn. Start and finish the rows at the heel of the flip-flop.
<b>Embellishment Options</b> <i>Sprials</i> Create two 2" (51mm), four 1" (25mm), and four 3/4" (19mm) spirals for each pair of flip-flops. Glue the spirals to the top of the wrapped flip-flops, starting with the largest spiral at the center, adding the medium spirals to either side, and then finishing with the smallest spirals.
<i>Crazy Fob</i> Cut twenty-four 5" (127mm) strips. Wrap a 10" (254mm) strip around the center of the 5" (127mm) strips and tie the bundle to the front of the flip-flop strap, wrapping the tie strip around the strap twice and securing with a double knot. Trim the strips to the desired length.
<i>Bow</i> Wrap some yarn around your hand three times, leaving some extra loose at the beginning and end. Remove the bundle of yarn from your hand. Form a bow by tying a 10" (254mm) strip around the center of the bundle. Trim all four loose ends to the desired length and glue the bow to the front of the flip-flop strap.
