Here is a great tutorial my friend Cindi made for labels - this is for care of the quilt, but the technique is the same for personalized labels.

Cindi also made another tutorial that shows how you can utilize QR codes and smart phones to put an identifying label on your quilt that helps to identify it and bring it home in case of loss or theft.
