Amuse Foosh brooches have a magnet on the back, with a second magnet that goes inside your clothing to keep the brooch in place. This prevents snags and pin holes that can be caused by regular pin-back brooches. But since you can wear these so many different ways, maybe brooch isn’t the best term for them?(Click image to view as larger PDF, which you can print or save.)
Since it is a magnet, you could even use it on your refrigerator. So maybe we should call them Pieces of Flair? Suggest a name in the comments. If your suggestion is selected, you will win a free brooch!
