It seems I'm the lone person who attaches labels on the quilt by machine after quilting. My hands don't like to hold a needle and it's painful to maneuver the needle as well.
So far, no one has complained.
I did try putting the label on before quilting once. It turned out I put it on too low and wound up cutting half of it off after quilting. That took me about a minute to get over, then I attached a new label over the remaining half by machine, then bound the quilt.
