starch. Last time I fiddled with a sheer I saturated the fabric in liquid starch (the kind you get in the laundry section of the market) set the fabric on grain and let it dry. Then I cut and sewed everything. It felt like I was working with paper but I had no trouble and the starch washes right out wen I'm done. I've been told spary starch and an iron work as well but I had the time to use the liquid.
