I began my quillow today. I never used the fusible batting before and am confused. I ironed it on the fabric according to the directions, but I got a sticky residue on my ironing board cover. Did I do it right? Is there a better way to do it? If I had ironed it with the batting side toward the iron, the iron would have been covered with the sticky residue instead of the ironing board. Did I do it wrong? TIA
