Hand-forged Brooch with Spiral Ends

How is this ring fibula closed? Stitch into the fabric at the needle where the ring fibula is to hold the garment. Then thread the needle between the ends of the ring fibula and turn the ring of the brooch 90 degrees under the tip of the needle. When you let go of the ring, the fabric immediately presses the needle against the ring and the ring fibula remains closed. More information...
