I was able to post at my other post, see attached link. IH, I have 12 sizes layed out with a size common that will also cross-scale. I started with my 1/8th then 1/10, 1/12 and 1/14. The samples you see, will each have four different pitches all together. In order to make this hobby more affordable and accessible to more people, a standard will have to be set and I am willing to take on that roll if it allows more people to enjoy it and is needed. I hope I am not doing this link wrong.
