1。 串珠怎末开头结尾？

2。 我看有些JM用金属链子穿的很好看，这些金属链子是从哪买的？穿的时候是不是像一般的线那样串？

最近看了JMS 串的项链真是心动啊, 恨不得马上买些珠子来弄弄

I just needed to know it myself too. This is what I just searched

As to the chain, I haven't done it yet but i think you can go and buy chains (michaels, online stores etc)
cut it to segments, and connect them with the loops on the beads. e.g. http://www.artbeads.com/brcahone.html

If you are a total beginner, try the kits as I recommened
