Hi there! welcome; glad you're enjoying it here.
I couldn't get anything at the url-link you posted so I cut off the tail end & tried again ... is this the pic? ::
www.tat2designs.com/images/necklaces/coin/T2N151GR.jpg*IF* it is ...
okay below are some possibilities for making it ...
although me? eeeek! think I'd just go look for a sale on something similar to it in a store!! but then I'm extreeeeemely lazy & not very creative... lllol sad but true ...
~~ FIRST you need a bunch of some ROUND THINGIES with holes.
I can't tell exactly what *those* round things in the pic are -- do you know?
Metal coins or some other type of metal discs? a type of side drilled coin pearl or other natural mineral or organic material? textured plastic discs? some kind of paillette? (a paillette is more-or-less a biiiig "sequin" type thingie) ... ...
well something like thosethings, anyway.
Whatever round flat thingies you care to use :
Unless you intend to drill holes in them yourself (morrrre tools/time/trouble?? lol) , just look for something that already has the two holes drilled through each side from top to bottom -- & of course the two holes do need to be be directly opposite each other.
~~ SECOND, obviously you need CHAIN.
Two ways to do this.
- For Method [1]-Make chain , below, you need two pairs of fairly small needle-nose pliers.
- For Method [2]-Buy premade chain , below , you need two pairs of needlenose pliers 'and' a fairly small pair of wire cutters -- best quality you can possibly afford (in jewelrymaking 'tools' are reeeeally not the place to cut expenses), and easy for you to handle, and with fairly small jaws.
[[[[*PLS NOTE* : had to edit this to change the tool after the word 'and' to *WIRE CUTTERS*. If you read this before I edited it, you may have been confused because at first I had mistakenly repeated the word pliers.]]]]
METHOD [1]-MAKE CHAIN ::
Buy a **whollllllle BUNCH** of metal jumprings (these are metal-wire circles or ovals that come in various sizes and are pre-cut in one place to allow you to open / close them) ...
and make your own chain by linking them.
You'll have long lengths of jumpring 'chain' punctuated by a couple of round disc thingies hgere & there. The discs are easily added by closing a jumpring into the hole on each side & putting only one or two jumprings between each disc, then continuing on with the longer lengths of chain.
((btw ... you can also MAKE your own jumprings out of metal *wire* if you like -- to me that's simply adding morrre time/morrre effort lolol -- but yes it can be done!))
Make the necklace long enough to double around your neck & you won't even need a clasp. Just use a piece of thick string to help you decide the overall length you want. Then measure wherever you want to add the discs, glue on little cardboard circles or use magic marker to mark those places, and you'll have a rough template to check your work against & keep you on track.
Jumprings are probably among the least expensive 'findings' in jewelry-making (unless you plan to use solid gold jumprings?!) ... and they're readily available at all crafts/ bead stores, whether bricknmortar or online. Usually come in silvertone or goldtone base metal, gold or silver plated metal, sterling, and-or copper.
Obviously the bigger the jumprings, the easier they'll probably be to work with. And, you could mix oval / round shapes & maybe even "mix metals" to make an interesting chain.
~~~IMPORTANT :::
The right way to open & close a jumpring is to move the two sides gently *sideways*, in other words : "past each other" to open, then back to the original position to close ....... NOT to pull the two sides of the jumpring apart and directly away from each other.
The pull-apart method can stiffen or weaken the metal which can cause it to break. Sometimes that will happen immediately, but even worse, sometimes it happens much later (e.g., after the piece is finished & while you're wearing it!).
Reason for two needlenose pliers with this method :
To do the correct 'sideways' motion for opening/closing, some people find it much easier & quicker to hold each side of the jumpring with a pair of pliers, instead of trying to use fingers & 1 pair of pliers.
METHOD [2]-BUY PREMADE CHAIN ::
Simply buy a bunch of metal chain (or pre-cut lengths of metal chain) & 'insert' the round discs into the chain.
To do that, you use the wire cutters to make one cut in one side of a link -- then use the needlenose pliers to open & close it into the disc holes.
It's exactly as if you were using jumprings in Method [1] above *except* you're only having to open-close a few times for the discs, instead of many mannny times to actually 'create' the chain.
~~~~IMPORTANT : for OPENING-CLOSING links in a chain, follow SAME WAY described in the section marked important in Method [1] ABOVE. Same principle/ same reason applies to metal chain links as well as to metal jumprings.
Of course, pre-made chain might be rather more expensive than a whollle lotta jumprings; you'll have to decide yourself if expense or other advantages are significant.
When choosing pre-made metal chain there are a few things to keep in mind :
-- Some metals are considerably easier to cut & to work with than others. Just me, I find copper & sterling easiest, but of course sterling can get kinda expensive sometimes.
-- The ease or difficulty of cutting a link in chain also depends on the thickness of the metal AND on the size & style of the link. Sooo, just me now, I'd look for links that are fairly large,not too thick,fairly open, and simple in style as opposed to fancy.
-- Just as with jumprings, you 'could' possibly mix chain styles and metals to create something really distinctive; that's just up to yourown personal preferences, of course.
~~ SOURCES for round flat two-hole/opposite-sides thingies of various types , also for jumprings , also for premade chain :
-- Browse through a few large crafts stores &-or bead shops in your area, and also ask for help, in finding the particular materials/ tools above...
I know you said you already did but I'm not sure you were looking for / asking for those particular things? (also if you can, print out that picture of the necklace & take it with you).
-- Also definitely browse through the 'catalogs' of the MANY good, reputable, well-known, large, reasonably-priced bead & jewelrymaking sources now online ...
