Combine 9/16" white rivets with ring binder mechanisms, a rivet setting tool and your own covers of choice to create your own binders. Push your rivet of choice through your cover and then through the mechanism, making sure that the flat face is on the outside of your cover. Then use the setter tool and a hammer to wrap the rivet, binding it to the top of your mechanism. Be sure to use an extremely strong and hard surface as your base, otherwise the rivet may not set properly. Binder rivets come in several sizes, depending on your cover thickness, as well as in either white, black or silver.
