If the fabric is light colored, I use the blue be gone or the purple be gone. You can also use architecture grade tracing paper, marked them and quilt the design on the quilt. Then very carefully, remove the tracing paper.

If there are any stubborn marks, I will very gently hand agitate. I find with the crayons I usually don't even need any soap, but sometimes those are harder to see because the color is less saturated. However, I LOVE the white Ultra Clean crayons for marking on very dark colored fabrics. After all the visible marks are out, I hang it or lay it flat to dry. Because I like to get my 100% cotton quilts shrunk until they crinkle before giving them to the recipient, I then toss it in the wash on gentle cycle/cold water with Tide Free and pop it in the dryer on low heat.

I've even ironed over the markers & still been able to get them out no problem. Because the crayons are wax, I would definitely avoid an iron with them because it will melt to your iron.
