Cozies for phones, mugs, or ipods are great tiny projects. I have two cats so I like to make little yarn mice or fish and stuff them with crinkly paper and catnip. A pair of wristers, legwarmers, or maybe a small clutch or purse are other smallish projects. Or you could always make a scrap blanket, there are quite a few on here that I've seen turn out beautifully.
