I am thinking that you are going to have to serge those edges of the satin, it loves to ravel. If you could find an heirloom or bridal sewing class (or book), that might be your best option on learning to work with this fabric.
I have a qult that my mom bought years ago at a big department store. It is all done in off whites, but is velvet, satin, and eyelet lace yardage. Beautiful but I rarely use it because of the dry cleaning it requires.
