Hey loked. Have you seen the free bed cloth example you can download here. As far as I remember, Izzy play a bit with the collision offset and depth, which tells maya how close you want the cloth to the the collision object. Otherwise hit F1 and read the section about cloth. Theres also a more advanced tut you can go through.

Hope thats help you a bit - otherwise. Just ask.

BTW, sorry for the late answer. I must have missed your post.
