Maybe I live in the dark ages, but I hand wash all my fabrics in one side of the kitchen sink, a few pieces at a time (depending on the yardage), rinse thoroughly until no color remains in the water in the other side, then squeeze as much out as my hands can stand, then lay out on old thick beach towels (several layers of fabric at a time), then roll up and squish it all together to absorb most of the excess moisture, then I take out, fold up, and take to sewing room to spend hours ironing the fabric (I procrastinate and wait until I have a bunch of fabric to wash!). I have very little trouble with the edges unravelling when I do the process this way.
