I’ve been finding that my magnet stash isn’t really up to holding cards, etc to the fridge. I’d made a few heftier ones out of old buttons some years ago and decided not to reinvent the wheel.
It’s not a terribly involved project – remove the pin, add magnets, stick it to something metal – but if your pin mechanism is enclosed, it will require some mean force & awkwardness to get it out. (Also, pliers.)
These little round magnets I got really cheaply at Walmart the last time I made these. Depending on the depth of your button/the thickness of the magnet, you may need to stack a couple to get them in contact with your metal object. Here’s one vs. two; most if not all the button magnets I’ve made have been two deep.
Thanks for looking! And thanks for all the swap art/happy mail that has necessitated these.
