I have made labels with the letters in my Pfaff, kind of hard for me. I've printed on fabric with my computer and fabric made for printing, worked very well. Written on fabric with a Pigma pen which is permanent and doesn't damage fabric. I use scrap fabric from the quilt to border the label and sew it into the binding on a
back corner. i include the name of the quilt, name of recipient, my name and the date and towns where we live. I do this after reading so much from people working with old quilts who try so hard to figure out where and when they were made and who made them.
