I've read that you should always put a label on a quilt. It should have at the very least: your name, date it was finished,your city and state and the name of the quilt. If you also want to include who it's for or anything else, that's fine too. I press a piece of muslin to the shiny side of a piece of freezer paper. This makes writing on the fabric very easy. If you draw lines on the other side of the freezer paper first with a permanent marker, you'll be able to see thru, if you hold both up to a window in the daylight. Place the paper-backed fabric on the glass and make your label. You can write/print your words on straight lines. Peel the freezer paper off after you're done. I use a fabric pen, set the ink by ironing. If you have no fabric left from the quilt top, then you can just turn the edges under and hand stitch in place or use some other fabric that's similar or maybe a solid that picks up a color in the quilt for a border around your label. Hand sew it on and you're done.
