I would use a piece of fabric and a Identi-pen(permanent marker) and write out the whole story. Name of the pattern, possible date made, anything else I could find out,and hand stitch it to the back. Even it the label was quite large, I don't think it would distract and would be a history for years to come.

Thank y'all for your input.
Once the label is finished, I'll post a picture.
Just hope the label doesn't totally cover the back!! HA. :D
