The Infinity Loop

1
Drape scarf over shoulder so that both ends are equidistant.

2
At the very bottom of both ends, tie an overhand knot.

3
Tie another overhand knot to ensure that the first knot does not slip.

4
Take the loop (shaped like an "O") and twist it so that it's shaped like an "8".

5
Drape the bottom loop of the "8" over your head.
