@Patrick Markey Now that I am level 2 I have just gained access to the 'Resources' page, I will have a look at it when I get a chance. I like the idea of stickers or labels but the QR code is pretty neat too. I also like the idea of a business card with all the string and tension details on the back of it, but again, you would potentially be making it easier for other stringers to take your clients. I currently make use of a small lable printer which I use to label my own racket with things like type of string, tension and date of stringing. It's just for personal reference really and in case anyone ask what my current setup is.
