Store them in air-tight containers such as Zip-Loc Bags or Tupperware with anti-tarnish carbon strips and keep them away from anything acidic or sulfuric. A rubber band, for example, will turn silver black. Paper and cardboard will also tarnish silver, unless it is acid-free.

Thank you for your inquiry. Artbeads.com offers a variety of special charms that are just for this purpose. If you go to http://search.artbeads.com/?lcr=1&q=rosary&u1=q&view=&x=0&y=0 you will see the many different charms that we offer.

Traditionally, you would string them on twisted silk thread and knot between each pearl. There is an excelent thread with a needle attatched sold on this site...Griffin Silk Cord. That's what I use and with a little practice, it's easy to make the knots evenly.

You could also use a stringing cable. Some use a small seed bead in-between glass pearls to look like the knotted method. This wouldn't be as flexible as the silk cord which has the added benefit of security should the cord break...the pearls are still yours and not scattered all over the parking lot. (voice of experience!)

you have a lot of questions rolled up in here so I will try to take them in order. Silk cord is usually used for pearls. Usually the inside of a pearl is smooth enough not to create cuts in silk cord plus the cord can be knotted between pearls to create a non-abrasive surface between each bead as well as adding VALUE to the resulting piece. Beadalon makes a knotting tool if you wish to learn to go this direction.

Natural stone beads can be somewhat abrasive inside and can cut silk cord so I prefer to use beading wire for most of my components other than pearls. I frequently use beading wire for pearls as well unless I am going to knot.

The silk cord with the needle at the end can be sued quite well with seed beads as well. These are made of glass and they work well on silk as well as wire. They are tiny and the needle can help to load a few at a time.. Check out the learning center at ArtBeads for more general information. A subscription to one of the beading magazines can teach you a LOT about beading without having to spend a lot of money on classes etc. I especially like the "bead Style" magazine. Have fun!!

If you are using jewelry wire to string your project, you can crimp the wire directly onto the loop at the end of the barrel clasp. If you are using chain, you can use an open jump ring to attach your chain to the loop on the clasp.

Depends on the style of ring - you could use fireline or Nymo for peyote rings; stretch for stringing beads; fireline for right-angle crystal rings;etc. etc.

You need to use crimp tubes with loops for the leather ends. The leather is inserted into the tube part of the piece and the tube crimped to hold leather in place. Attach a clasp to the loop of the tube.

If you prefer natural stone beads, try amazonite with accents of hematite, paua shell, gray pearl, czech glass, swarovski crystal.

The easiest way I can think of would be to use a clasp for 3 strands. Twist the strands and attach the ends of each strand to a loop on on the clasp.
Once you have the twist the way you want it, attach all the strands from one side, then all the strants from the other side.
