Get your blog linked on a lot of other blogs for a start. Do you sell wholesale to local shops, not just quilt shops, but book and gift shops, too? Is there a local group of small business owners you can join? Craft organizations? For instance, the local farm stand in my town also sells works by local artisans. Is there something in your books that you could do as a tutorial on your blog to get more traffic? It would help to give suggestions if we knew more about the type of books!
Edit: I went to your website and really like the idea of the books...but is there any place that you show the quilt patterns featured in each book? I mean, like pictures of the quilts? I just don't see any. Thanks.
