Lots of good ideas here! I made a baby quilt, probably 5-6 years ago, that I used a ball point for drawing circles, then sewing muslin onto it for a turned appliqué (I'm sure there is a term for this..). I was done with it, quilting and all when I realized that some of the ink was coming through. I saturated it with hair spray and washed it...I think I did that 3 times before it was totally removed. That quilt had a lot of work in it and it was a gift, so was determined to get it fixed!
