I use pre-printed labels all the time but hate trying to tuck in all the little ends. What I do is stitch lightweight stabalizer to the front of the label using a 1/4" seam all around, slash the stabilizer to allow you to flip it to the back, iron and this encases all the edges. You don't even need to stitch up the turning slash as it will be on the back and hidden. With all the edges encased, it is simple to top stitch the label on by machine or hand stitch it if you wish. The lightweight stabilizer just gives the label a little more body and I often do my writing on my label after I have it prepared as it is easier to write on it then. Light weight stabilizer (mostly used for embroidery designs) comes on rolls about 10" wide and is not that expensive. A roll lasts a really long time and I can cut out enough for two labels per width. I often prepare and stitch labels ahead so that I can just grab one and write. This method of backing your labels also works for any label that you make yourself. Some people use used dryer sheets for the backs of labels but some don`t like the dryer sheet residue or are bothered by the scent so a roll of stabilizer may still be best.
