I like to put not just labels on my quilts, but also a QR code. The label tells the year, my name, the quilt name, etc. The QR code is a link to a post on my blog which has more in-depth information about the quilt, such as progress pictures, design choices and changes, and so on. If the quilt ever gets lost or stolen, I have the ability to add that to the blog post, so if someone finds the quilt, they can scan the QR code, learn that the quilt is missing, and contact me so I can arrange to recover the quilt.
I've had nothing but good feedback from people who have received my quilts with QR codes, they seem to love the "behind-the-scenes" info they get.
