The taffeta is Polyester, I am using a 70/10 microtex needle. The taffeta is almost a medium weight. Not as thin as a batiste and not as thick as a twill. I have discovered it is easy to melt with the Iron. It hasn't water spotted, perhaps because I washed it before cutting. I knew how it would be treated after it one use. I hope it works out nice enough for her to sell on e-bay when she is finished with it. (
In my dreams). Thanks Marty for loooking it up. Cheryl, it is that stuff that we had before nylon that sings when you walk as the fabric rubs together. little girls party dresses were made out of it when I was a child. I don't remember it puckering when Momma sewed it on her old Singer.
