In hues of blue, gray, and cream, these scarves evoke the look of men's suiting. The stripes are created with pieces of yarn needle-felted along the length or width of the scarves. 

The navy scarf shows how needle-felting looks on both sides: The design on one side is sharp; the other, blurred. As with the roving scarf, you can dress up a store-bought one or use unhemmed woven-wool fabric cut to the size you desire.
