Some of the satins are dry clean only and tend to melt with ironing since they are made with acetate. So check the care label if you are planning on quilting since we tend to press at every step of the way. Also on knits and slippery fabrics like satin use a smaller needle like a size 11 and use a ball point tip. That way the needle pushes between the threads. Satin tends to runs at times. Beware.
