How do I get jumprings to close securely and stay closed? Several have come loose, allowing the attached object to come off and be lost.
You can solder the jumprings closed with easy solder and a butane torch, or reference the ''Opening a Jumpring'' how-to video and illustrated instructions.
When I'm working with heavy-gauge jumprings (I recommend you work with the heaviest possible), I repeat the closing motion three times, moving the ends of the jumpring ever slightly inward, to nearly overlapping, as I move back and forth. This motion creates tension in the jumpring and forces the ends to push inward.
