I make most of my quilts as gifts and I always label them. I put the name of the recipient, date, pattern, and my name and city, state. I normally type the label and print it on paper and then I trace it onto plain fabric and I used an indelible pen to write on the label. I usually machine embroider a design that ties in with the them of the block first and then I write the information. Finally I cut it to size and sew it to the back of the quilt. I haven't made a quilt for myself in years but I normally put the pattern, date and my name, city, state on the plain label. Years from now my children, grandchildren and great grandchildren will know the names of their quilts and when they were made.
