I use 'sort of' the same method as SandyinZ4....EXCEPT instead of sewing the label to muslin I sew it to lightweight interfacing, sewing the right side of the label to the bumpy side of the interfacing. Then snip a hole in the interfacing and turn right sides out. Position your label where you want it on your quilt and press it on to fuse it to the quilt. I use a press cloth when I do this. Now the label is firmly attached, has no raw edges and is ready to handstitch on.
