I try to add label if it is a special quilt, particularly for my family. I first used the alphabet stitches on my machine. It is so involved, it took me longer for the label than it did to make the quilt. It was a new baby quilt for one of my DGDs. On the final version I misspelled my last name! And I just put it on anyway, it was only one letter short! Then I tried printing on fabric using a font on the computer and that worked well. Not too difficult. More recently I heard some discussion on handwriting with some type of permanent ink. Some people like having a person's handwriting and I do, too, such as my mom's recipes. So I've done a couple using a Pigma pen. Hopefully, it will last, not too sure about that yet. I usually try to incorporate part of a block or even some of the binding to go along the outer edge. I work them into a corner of the back as I hand sew the binding. For the babies I use their name, birthdate, and location. Older kids I leave out the birthdate. I include my name, location and date the quilt was made.
