I always include the name of the quilt, my name, the size, date (month/year) and any other pertinent information, especially the name of the person who inspired me to make the quilt or the name of the person the quilt is for. I write the info with a sharpie pen and press it before hand sewing it onto the back of the quilt. When considering putting the quilt in a show, I sew the label on the quilt before quilting or write the info directly on the backing.
