I am still searching, but came across this one for Baby Mary Janes. Go down the page just a bit to find the free pattern. Just click on each picture to enlarge it to print it out. It also has pictures of the process in making them.
Hope this helps. Will keep looking for more...darn I saw another just a few weeks ago, but I can't find it now. Now you have me on a mission. :>)
