If you are using a jump ring, use two pair of pliers or a jump ring opening tool and twist the two ends away from one another, reverse to close. Never pull the ends straight away from one another. For instance, with the opening facing you, you would pull one end toward you and push the othe away from you.

2. You want round nose pliers. Having added your beads et al and cutting the pin to the needed length, bend the end of your pin at a 45 degree angle then grabbing the end of the wire curve around the tip of your pliers moving down the wire to complete the loop.

I would actually wire wrap for added security. In stead of cutting the pin follow the basic directions above, but form your loop a little high on the pin and continue wrapping the end around the wire 2 or 3 times, keeping your wraps close but not overlapping. Of course, if you do this, you’ll want to make your own eye pins from scratch so that both ends are wire wrapped.

3. firemountaingems.com or beadandbutton.com should both have video tutorials for all of this. You might also consider your local library for books or periodicals on the subject as they would contain photos and diagrams that would be most helpful!

I hope this helps! Good luck and happy jewelry making!
