A lightweight fusible stabilizer is what you want, non-woven none a oven stabilizer is kind of like paper ( like dryer sheets) woven is more like a fabric ( like very thin muslin) either one is OK to use. When working with very thin/fine silks I tend to use the non woven, and i use the woven more often with heavier ( like dupioni silk) fabrics. But I have used what ever I had on hand. I think the wovens make the silk easier to cut, which to me is the greatest challenge when working with silk. Also, use a good New Sharp needle in the smallest size your thread choice will allow
