Help with Resin....

[dairy-bitch.livejournal.com]

I saw these really cool bracelets and necklaces with pictures wrapped in resin at http://www.naughtysecretaryclub.com
and was inspired to try and make my own.

The problem is I don't know where to get resin or how to work with it. Can someone tell me or link me to a site with resin instructions please?

Thanks a bunch!
