Moving this directory from the legacy forum.

As they are widely spread and I’m not sure whether the people who are interested in them can find them easily, I’d like to make a list of links to every topic regarding handmade cards and mail art.
This is a WIKI! That means that we all can edit this post, add new topics or change broken links etc. But you can also post a comment and I’ll add new topics that you found.
I will also write a post for all new additions to this wiki and if you want to follow to see what’s new, you can just track or watch this topic and then you are notified by every new post.
