i purchased some coloring fabric last year to use in quilts for my grand daughters. the fabric is specially treated, it's recommended you don't prewash. color and set color as you would any coloring of fabric with crayons. my only issue is the girls had decided watercolor painting on glossy photoprinting paper their daddy gave them was waaaayyyy more fun than coloring. even if it was fabric with "awsome" space ships & aliens
