There are some great online rug groups you can join - free or nominal fees - that are well worth joining if you don't have access to a rug group in your area where you can get help, information and some social interaction. Do take a look that them...you'll find the members very helpful and you'll be given advice and help from some excellent rug hookers and fibre artists!
Rug Hooking Daily (free) - based in New Brunswick, Canada offers a huge amount of information and resources for free. Find them at: http://rughookingdaily.ning.com/
Yahoo Rug Hookers (free) - US-based rug group that includes a number Australian members...they get a bit too "off the subject" for me sometimes but do offer some useful ideas. They are at: http://groups.yahoo.com/group/Rughookers/
The Welcome Mat (annual fee about $25/yr..payable online) - from Ontario, Canada offers classes and a huge range of information and support. Find the site at: http://thewelcomemat.ning.com/ ) you can also take a "tour" of the website (without joining) on YouTube at: http://www.youtube.com/watch?v=KjcSM5oyahE
Gene Shepherd (California) offers a free blog / website as well as a subscription site for the Internet Rug Camp. I think the IRC is worth the subscription for at least a year so you have access to all of his extra videos that aren't available on YouTube. You'll need to decide how much information you want and it might depend on how much access you have to rug groups and teachers in your area. Have a look at Gene's free blog /website at: http://www.geneshepherd.com/Genes_Intro/Welcome.html
That should get you started! If you need other specific information and can't find it yourself on the Net, let me know and I'll see if I can help.
