The scarf hat is a vintage pattern from a 1940's crochet magazine but I knitted it in a stockinette stitch and finished it with crochet.  The yarn is a "baby cashmere" which mostly polyamide. Hmmmm!  But is is soft and pretty with it specks of olive, gold, and fuschia on white.  It will fit head sizes 21" to 22".  It is one of a color.
