I probably don't understand what you're trying to do, but if what you're looking for are different fonts that you can trace to use as applique...why not use Microsoft Word (assuming you have the program) to type letters out and change the fonts? You can adjust the size to fit the project. You can also download free fonts that will work in Word.
If you don't have Word - Google Docs (which is a free online program) will do the same thing.
