Raising my hand... I prewash in hot water with a warm rinse and then dry on high heat because I want maximum shrinking before I start to cut out a quilt. Besides, there's no guarantee at all that the finished quilt will be washed in cold water by a new owner even if you (strongly) suggest that's how they should care for it.
If my batiks are still losing dye after two (gentle) cycles, I add Retayne to set any remaining loose dyes. It's never failed me. There's no way I would ever stop using batiks.
