Andrea,
Since you seek to generate income from your instruction, you might, as others have done, create a video (DVD) that you then sell.
Alternatively (or additionally), you could try using an online streaming video service (IF your internet access is fast enough) such as
http://ustream.tv. This would enable you to offer classes to anyone anywhere in the world with a decent Internet connection.
I have taken painting classes that use this service. What is really great about it is that you could do a "live" workshop (although the time difference might be a bit challenging for us here in the U.S.). The "students" watch you through online streaming video; there is a "chat" window that allows students to send you and each other questions and comments that you can answer through the video. And if you really want, you can have students take and email photos of their own work, and you can then provide feedback and suggestions to them.
Here is the URL of the painting instructor I have followed:
http://www.ustream.tv/channel/dave-the-painting-guy
There you can see examples of how he uses this service. One of the things he used to do was simply turn the camera on while he paints and we get to watch for free. Then he would periodically offer paid workshops. I took several of them; it's great.
As you can see, he leaves "recordings" of his past sessions so you can watch. If you're watching live, there is a chat window you can use with other viewers. I think he uses the free session (where we simply watch and he periodically talks about what and how he does what he does) as a form of marketing-- a "teaser". Then the paid classes are all about us.
He also records his workshops, and you can pay to view these.
I did a search and found this recorded video on hand quilting:

The only drawback of this service is that it really does require a strong, fast Internet connection for both the deliverer and the audience.
And I think it's free (one simply has to accept the advertising).
Best of luck to you.
