As a retired high school teacher, I have former students who have settled in all sorts of occupations. One is a very good leather "maker" and I want him to make me a guitar strap. I have no idea about measurements. Each of my three Guilds have two buttons for attachment. Are the demensions, pretty much, standard or owner specific? First few things which popped into my mind were length, width, buckle, adjustment, ease of installing, and is it legal to use the word "GUILD" stamped into leather for others to see? What do I tell him, beside color, when he ask, "what do you want and what do you want stamped on it?"
