I don't pre-wash my fabrics anymore unless I'm using Red with some sort of white. When I did wash big batches, the best thing I found was to trim a small piece off each of the 4 corners...and it prevents the raveling. You'll have a few threads, but not enough to get tangled up.
I've also just washed it, and then hung it to dry over hangers or towel rods...or shower curtain rods, and didn't put it in the dryer.
Too much trouble for me now, and I like sewing with the crisp new finish & feel of new fabric.
Why are you washing it??
