I also iron the fabric to the freezer paper. I first cut the freezer paper so it fits in my printer. I then iron the muslin to the freezer paper, select pattern (using free labels on the
June Tailor site) and then print. After printing, I iron the label a couple of times, as suggested, to set the ink. Works well for me. I have not seen any of the label on quilts I have made and don't know if the ink lasts. This is because I usually give my quilts away as gifts.
