This is what Clover suggested to me when I couldn't get the BLUE Clover chalk out of the quilt I made. CALL THEM and complain!! I always used the white with no problem especially on dark borders. I HOPE something works for you. And yes, men don't see the things we see but even a non quilter might not notice the chalk. Good Luck !!
