One of the first writing conferences I went to, I ordered 250 free business cards from Vista Print. Having my name, my website and the word writer on a business card was an important step in telling the world, I am a writer. The cards are free if you want Vista Print's logo on the back which I didn't mind, but you can also pay a little more and design a unique card for your blog, website or just for your desk to remind yourself that you take yourself seriously as a writer. Vista Print has 42 FREE designs to choose from, the printing quality is great and the shipping is fast. They also have a section on their website with links to other free products to try because they know you'll be back to buy more of their great products.
