I'm holding my link parties over at The Sunburnt Cow. The parties run every Wednesdays through Sundays. You can link up just about anything: what you've made; what you have for sale (as long as it's in a blog post); anything antique, vintage, prim - whether you've made it or not; even recipes. So let's party!
I feature everyone on my All Thumbs Crafts blog, which gets the most exposure of all my blogs (200-300 page views per day). This is a great opportunity since an entirely different audience will see your blog; they may like what they see and start to follow you. That's basically Marketing 101 - getting a wide variety of followers/readers. Of course, that'll only be welcomed by you if you want to have diverse followers; if you want to keep your blog audience of a very narrow variety, then it's best not to link up.
