Magnetically latching multi-tool holster

Step 7 Cut magnet cover fabric

Cut a piece of fabric that matches the contour of the flap, and allows enough length in all directions to surround your magnet(s). I used some cotton duck scrap because of availability, I would imagine denim would work well too. Anything thin and tough. Thin fabric allows the magnet to get close and exert as much force as possible on the tool, and tough so the magnet won't tear through as you open the flap.
