Is this what you are wanting.
Thanks you very much
perhaps you can use these letters, they are free
Unfortunately unlike built-in alphabets you can not arrange the separate letters in your machine. The only way I can think of when you don't own embroidery software is printing templates of the letters, cutting them out, arranging them on your fabric and marking the centres for correct placement, just like you would combining other designs.
Come to think of it I wonder whether you could print templates without software!
Not much help, is it?
Have you looked at Fivestarfonts for large free appliqué letters, they have several in various sizes.
