I start by going into your word processor and working up the decal that you want to have with the font size and type Times New Roman Bold (48) for the model number letter, Times New Roman (36) Normal text, with the desired spacing between the two. Print out your choices on normal laser paper until you have exactly what you want. Since you will be using a full sheet of the rub on paper, then you can put as much as you want on it. No reason not to have two or three of these decals on the sheet in case you spoil one. And you can add wire gauge sizes in a small font size if you desire, all on the one sheet. For my Paulello stringing, I notate the wire type along with the gauge size. The sheet comes with a carrier sheet and adhesive sticker paper. Place it in the printer and print out your masterpiece. Cut it out and place it on the plate, and rub it on. Follow the directions, and there is a two minute how to video on the website. If you screw up, it can be removed with water or heat. You should be able to clear over it. If you have a color printer and some publishing software, you could make up your own decal to place somewhere in the piano.
