I’ve seen several very good examples of using cork for pads. They don’t absorb any water, provide great traction and last. Guys covered whole top of the board.
As of eco friendly - people forget that not using hot shower, using least tap water e.g. not flushing, not having kids, not traveling, not using transportation, not having manufacturing - are easiest eco friendly things to do
But realistically, megapacks of 3oz tiny water bottles are first thing which should not exist on this planet.
Cut the pretty cork pad, post pics!
