If you only know one scarf knot, the Fashion Knot is the one to know. It works well with both thin and thick scarves, and looks great with long scarves. If you pair two scarfs of complementing colors, the knot intertwines them simply and beautifully. To tie the knot, just double your scarf behind the neck to make a loop. Feed one end through the loop going over and one end through the loop going under. Leave the knot loose or tighten it up a bit.
