How about a cotton hand towel/face cloth set like this one? Very handy, and very giftable!
(The towel buttons around the towel bar, preventing it from ending up on the floor all the time!)
Here are my project notes/pattern (free) for it! In addition to the yarn I used, you could easily substitute Lily Brand Cotton, Sugar and Cream I think it's called.
Here are some face cloths I knit up, using one ball of Lily Brand Sugar Babies cotton yarn.
Garter stitch face cloths are great! They really scrub off the facial cooties!
