The November 2009 issue of ARTnews has a very interesting article about the branding of Andy Warhol. Warhol died in 1987 however as a testament to how well he branded himself the demand for his work is stronger than ever.
I know it seems to be anti-arts/crafts to be talking about branding but establishing your company/body of work as a brand is one of the best ways to generate blockbuster sales and be able to charge higher-than-market for your products.
Branding doesn't mean the handcrafted nature of your products has to be compromised; merely that your business' name becomes synonymous with the type of product. For a broad example, think wrap dresses and Diane von Furstenberg, wild prints and Marimekko, or the twisted cable jewelry of David Yurman. Arts and crafts example - Myra Burg and her silent oboes
For more information about branding, the article, Warhol, Inc., is available online and this excellent Guide to Branding by About.com Marketing Guide Laura Lake.
