I just finished a project with batiks. I prewashed them all: purples, reds, aqua, etc. Everyone of them ran color to some extent. Purples and reds are the worst. I used Retayne in the final rinse to set the colors. Now I know this jacket can be washed. It's a hard lesson to find that one color has bled onto another and ruined all your hard work. Batiks are the worst offenders for bleeding.
