I suggest we use 9 products + 9 words + 9 techniques.
Now of course, feel free to adapt this to fit your style. You can choose "buttons" as one of your products and use as many as you want or "1 button" and count each button as one product. I know you will probably fall for the former, but I think it'll be interesting to see where this challenge leads us. It will give us freedom to play. I can't wait to see what you come up with.
