Industry standard white on black size labels from NB to 24MO.
You'll never outgrow the need to clearly label your baby-sized items and projects. These size labels are meant to be folded in half and sewn into a seam. In many cases sewists first apply these to the primary brand label and then attach the label set as one to an item.
Labels for NB, 0-3 MO, 3-6 MO, 6-9 MO, 9-12 MO, 12-18 MO, or 18-24 MO sizes.
