Buy June Taylor's fabric paper; then go to your laptop and pull up Microsoft Word. Write what you want; even get clip art. Run the fabric paper through your INKJET printer with the fabric side down in the paper tray. June Taylor fabric paper comes in fusible and non-fusible. The non-fusible, of course, will have to be hand stitched onto your quilt back.
I use this method all the time, and am forever getting compliments on my quilt labels. I will say, though, that because the sheets are 8 1/2 X 11, I wait until I have between 4-6 labels to make, thereby using up completely one sheet of fabric paper. Sometimes I make labels for my UFOs. It sort of gets me in the spirit to complete them!
Hope this was helpful!
