I made some needleminders with some unused enamel pins (from Fossil Forager) I had lying around. This is entirely as simple as it sounds: you pull the pointy part off and superglue a magnet on. If you're working with a magnetic pin, you'll have to stick magnets to both sides to stick a needle onto the front. (Not great for aesthetics, but I don't care about that!)
I don't have much use for pins, but the magnets don't compromise wearability, so you could still use pins that you've converted in this way. If anything, the magnets are probably beneficial since neodymium magnets are ludicrously sticky.
I found this recipe for pecan pie brownies on the Times last week. It was a journey filled with many trials and tribulations and I ended up having to make them twice, but at the end of it I had some damn good brownies. I modified the recipe for my own purposes, and now I share it with you because stealing from the NYT is always morally correct!
