I’d like to add that the felt without the adhesive (coasters on the Riv site) are my personal favorite choice as they allow for easier reuse. If applied over cotton bar tape, using twine or rubber bands or whatever else you could think of to hold in place, they wont move around. The felt clings to the cotton well enough on its own without the need for adhesive. It clings very well to Oury grips and ESI grips too.

Awesome posts! i'm inspired to create my own design. in case you don't know, felt pads are currently available at SOMA, as well as Newbaums tape and twine.
