We use those small pet waste bags when cleaning out the cat litter and just throw the roll on a cabinet.

I’ve thought about making a holder/dispenser for quite awhile and decided to do it this weekend. I picked a piece of oak from my scrap bin to cut all of the pieces from. It was a quick, crude build. I snipped the ends off a nail for the pin and glued a couple of magnets in the bottom, since the cabinet is metal.

Does the job!
