Another hand quilter here who ends up with really dirty quilts by the time I'm done. I always toss mine in the washer, normal detergent, perm. press cycle. Then toss in the dryer on the perm. press setting as well. I prewash my fabric so don't normally use color catchers at that point. Although I've had to in the past. Had a green that just would not stop bleeding after being completed. Finally gifted the quilt with a box of color catchers and instructions to use them with each wash.
