I've been tying scarves like this for decades, and I don't know that I've ever seen anybody else do this! So I'm sharing with the world...
|The finished Infinity Knot.|
|For a square scarf, start with a standard bias fold. Excellent instructions for this can be found here.|
|Center the scarf at the back of your neck, and make sure that you can see the "open" part of your folds (this will make more sense later).|
|Cross the scarf in front of your face.|
|Cross the scarf AGAIN in front of you. Yes, each end of the scarf is now headed back to the side from which it originated.|
|Bring the small ends of the scarf back behind your neck, and tie the very tips of the scarf into a wee bitty knot. (and yes, that IS my hair...)|
|Tuck your wee bitty knot into the "open" fold area of your scarf, and then fold it shut. This hides the tiny knot, and leaves everyone around you completely mystified as to how you tied your scarf...|
