I found a pattern at: http://promotions.drgnetwork.com/newsletters/talkingcrochet/pages/TCNL2706_patt.html
There are more patterns on site for baby and others
Here is another pattern: http://www.crochetnmore.com/babywashcloth.htm
do a www.google.com search for more - on search line type
in baby washclothes+crochet and a list should come up for you.
Hope these help and good luck.

I like to sew a double thickness of a cute cotton flannel fabric and then use cotton crochet thread to crochet a nice edge.

You might try using Paton's Grace cotton yarn for the baby washcloths. It is DK weight, 100% cotton. Nice and soft, but more expensive than the sugar & cream. To me, it would be worth the extra expense for a baby's tender skin, to buy the Grace.

Sorry, no pattern suggestions.
