The Hidden Knot is a nice scarf knot to know. It allows a scarf to fill a lot of space on your chest and neck. It is best when tied in silk scarves. To tie the Hidden Knot begin by folding your silk scarf in half on the ends to form a large triangle. Wrap the ends behind your neck and then tie them together in the front. Take some material from around the neck and pull it up behind the knot and then down over the knot to hide it. You can also roll it slightly under the knot.
