In short, it is a wholesale bead/chain/jewelry/everything supplier.
I first discovered CJS probably a year ago through For The Makers, a now defunct subscription box that had great tutorials. Their site seems to be down, but this was the link to their blog post. I didn't have a tax ID then (which you need to shop there), so I squirreled away the post for when I decided to bite the bullet and get one.
I finally got a tax ID a couple months ago in November--and the first thing I did was look up CJS, but only to discover they lost their lease and are going out of business.
So, everyone out there, you have until the end of February to visit.
Years ago I wrote a Jewelry Basics Tutorial. I wanted to put together another basics tutorial--but on materials and tools.
It doesn't take much to start making your own jewelry (or more specifically, earrings). It's the options afterward that are endless. I started with a little kit which slowly over years expanded into a collection that is in no way portable.
These are the bare bones basics. Even if you don't want to start making your own earrings, these will be nice to have if you want to do any repairs.
