For table toppers or table runners, I usually use the pigma pen to sign the quilt.
For quilts I use Microsoft Word to create my labels -- I include a picture of me and the person I am giving it to if I have one. I print onto Printed Treasures -- usually printing 2 labels at a time. I include them in the backing and quilt over them.
I need to make labels for the quilts made by my grandmothers and DH aunts before there is no one who remembers who made them.
