I rolled two balls of sugru, planted them in the center of the coins, and squished the link into the middle, then shaped the squeezed out stuff around the base into a nice cone.. The actual links with the rotating bar arm are from a pair of cufflinks I *ahem* recycled (I never liked them). I removed the (hideous) visible part and thought to reuse the useful part in a DIY pair I would actually wear! Kerry, Washington.
