Be very careful regarding items from KaleCoAuto. Their Roundtuit, for example, is far more complex than is necessary. I have a local source for them. They're wood, smaller, smooth to the touch, and have instructions imprinted on them. They are not only designated as roundtuits, but also as wooden nickels (on the other side). They're far more desirable, and they give them away!
You can buy all manner of fasteners in the same place!!
