Mr. King, Thanks for your response! I appreciate your expertise; it is invaluable to a novice like myself who desires a really great outcome!

This may be a silly question, but is it necessary to use silk organza fabric? I went to my local fabric store but they only carry a 100% polyester organza. Would this suffice? Thanks for the great instruction, I can't wait to try it in a dress I am making.

Just starting to sew again after many years. I'm learning alot from Threads. Just the info I need to learn the techniques to make my garments look professional. Thanks!
