Hi,
Since I am fairly new to quilting, I was told that you wash all your fabrics. After doing this for several quilts, I got tired of all the STRINGS - now I use the steam setting in my machine, and steam the fabrics, since steam is hot, I believe the sizing and chemicals are released from the fabric, they come out damp, so I throw them in the dryer for 10 mintues. I then press them with a hot iron. Recently was told about using spray starch, made a baby quilt this week, and all I can say is "What a difference in sewing the seams" a little startch can make.
