Do you have some pretty yarn but don't think you have enough to make something? One solution is headbands. These are especially nice in the summer: not only do they keep your hair out of your face but being small they make great travel projects and they work up quickly.
The mobius bands are fun to make and the twist helps the headband lie nicely at the nape of the neck. These need to be stretched over the head so choose a yarn that will keep its shape. A wool yarn blended with cotton or linen will provide stretch and breathe-ability.
