Learning to make glass jewelry such as lampwork beads and fused glass is probably not the easiest of techniques to learn on your own. But, you don't have to because there are plenty of schools and glass instructors these days to help you learn this interesting craft. You may have to do some traveling, but there are lots of craft schools and artists teaching fusing and lampworking today. I've started to compile a list of glass classes for jewelry makers, which you can find linked under
Glass Schools.
