The Wire Artist Jeweller is a good source of wire designs. They have beginner and advanced projects in every issue.
They are a regular print publication ... you won't find a bunch of projects on their web site (http://www.wag.on.ca), but it is a good place to go to find out a bit more about the magazine.
Lapidary Journal also has Wire Projects in most issues. They have a web site, too: www.lapidaryjournal.com.
