I label all of my projects. (Generic) ones- meaning not made for someone special or special occasion may get a simple one — name of quilt, my name, City, state, date finished ( or at least the year) fiber content & care instructions.
when it is for someone special or a special occasion I do a more personalized label - still containing the above information along with the personalized information.
the labels might be embroidered, hand written with permanent fabric pens, designed and printed from the computer or permanent. I’ve used them all.
