1) Chains usually come in different types depending on the number and shape of the links used to make the chain patterns, and they have names such as Rolo (made of thick, round links) and Figaro (made of one long and three short links). Become familiar with the different types as you consider which will fit in with your design needs.
2) Avoid chain patterns such as the box chain or twisted rope chains if you plan to use your chain mixed with wire wrapping techniques. The links on these chains are too small to work with easily.
3) Plated chains can lose their plating over time. If you want your jewelry to last for a long time, go with sterling or gold-filled.
4) While thinner chain is cheaper, be careful not to purchase chain that is too thin because it can be difficult to attached wire or findings to sometimes. I usually try not to get anything that is smaller than 1.5mm.
5) Look for chain that has nice sized links if you plan to attach other items to the chain such as beads. You want to make sure your wire can fit through the links.
6) To separate chain links or cut sections, simply use a good pair of wire cutters. Literally cut out a link or two if you need a section of chain. If working with precious metals, save discarded links. If you cut them carefully enough, you may be able to use them as jump rings. Otherwise, save the scrap. Many metal jewelry suppliers will allow you to turn in scraps for credit.
7) If you plan to use a fair amount of chain, look for suppliers who sell it by the foot. Normally, the more you buy the more you save per foot. Ready made chains are also good to use sometimes because you can recycle the attached clasp.
8) Keep chains on rolls or wrapped around pieces of cardboards and stash in airtight containers like zip lock bags. This will keep the chains from tangling and also help keep down the tarnish.
9) If you plan to solder on the chain, make sure it isn’t plated because the heat from the torch will remove some of the plated metal.
10) Save scraps of chain, even if they are just an inch or so long. Very often you might find these come in handy to use as a necklace or bracelet extender or make earrings with at a later time.
