I have an Ellure and I bought larger alphabet sets for larger letters, there are also fancy (different fonts) available. My Ellure is older so it doesn't have USB hookup. I download the designs to my computer from the site where I bought them. Then I hook-up my magic box converter and card (the magic box cannot be used with the new 32 bit computers). I choose the designs (or letters) and load them on the machine card. The card is erasable so can be used over again for different designs. Newer embroidery machines have USB ports so the process is much easier, no magic box needed.
