Some fabrics just simply do not like dryer sheets. I made a dress from polyester fabric (many years ago). The theme for the dress was supposed to be Southern Belle. By the time I finished the dress, it had become -- well, it just needed to be washed. So, I washed it, put it in the dryer with dryer sheets, and it came out spotted all over. I washed that dress 3 times -- the stains would come out, but I kept using the dryer sheets to dry it because of static electricity, and every time, it came out with spots. I used a can and a half of Shout -- took out those spots every time, and every time I washed it, I put it in the dryer, but the last washing, I did not use dryer sheets -- spots were gone! So, I never used dryer sheets again!
