I'm washing fabric today myself. One load of darks and one load of lights. I just fold it from the dryer and put it away. I iron and starch when I am ready to cut it. Since I usually cut one fabric at a time, I only have to iron one at a time so it is not such a chore.
Some of us HAVE to prewash. We don't have a choice. Even the best fabrics are treated with formaldehyde and other chemicals. It has been outlawed in the manufacture of carpet because of fumes. It should be outlawed in fabric, too.
