Do you have Microsoft Word or another word processing program on your computer? I type what I want into Word and enlarge the font. You can go higher than the font size listed, just highlight the letters and size at the top and type in higher numbers. On my pc, 460 size font is about 4". You type the letters you need, print them out. Hold up to a window or light box and trace the fusible using the back side of the letters. When you fuse them, they will be right side up.
