I add my label to the backing fabric before I send it out to my longarm quilter. If it is a machine embroidered quilt, I will embroider an extra block allowing extra room for information I will want to add. (After the baby is born I would add the babies name, date of birth.) If I can I will embroider this information when I make the label. If it is a pieced quilt top, I sometimes make an extra block if there is room to add the information, but sometimes I will add an embroidered block to these quilts as well.
