How To Make Jump Rings without the proper supplies
First thing you need is the desired wire size and color. I prefer using smaller gauges like 16 and 18 and sometimes 20 gauge as well. The smaller the gauge, the thicker the wire, so the size of wire you use really depends on what you want to make with the jump rings. If your using them to make chainmaille jewelry, thicker wire would be better.
Ok so the second thing you will need is something to wrap the wire around. Again, the size is completely up to you. I like to use a pen or a screwdriver. A screwdriver is easier because it has a handle to grip onto while your wrapping. But again that's up to you, anything with a cylinder shape to it will work for wrapping wire around.
And finally the third thing you will need are wire cutters. The wire cutters are to cut off the excess wire when your done wrapping it. And also to cut out your jump rings. Craft stores and fine jewelry makers usually use a proper saw but this is a "How To" without the proper tools of course. If you don't own a jewelers saw, then you can go for the next best thing which are wire cutters.
Have fun and happy crafting.
