I am not a member any more but I have to say that I LOVED the kits I got from The Scrapbook Society.
http://www.scrapbooksociety.com for info.
If I recall correctly there is a different fee for a one month commitment vs. a 6 or 12 month commitment. You get to try a different technique each month - most of them were really cool - and all of the stuff that you need to try the technique is included as well as some really great papers.
Melynda has a message board that runs very similar to SCS, smaller though. And though most of the postings are scrapping related, you can easily cross-craft and stamp cards. Check it out!
