Combining two of my great loves ... Writing and shopping.
The Writers Store has books, supplies, articles about writing, online courses and more, including the cute mouse pad pictured above.* It's worth a virtual visit (or an actual one--if you're on the left coast they have a store in Los Angeles, CA). They also have an affiliate program, which means that Gienna Writes gets a little cut of the action when you go to the store through this site and make a purchase (either click on a text link in this post or the banner ad in the sidebar to the right). Plus, SCBWI members get 15% off of books and software.
But the best part of this site is the "articles" section, which is totally free. There's a ton of great content here, including interviews like this one with Shawn Lawrence Otto, who co-wrote the screenplay for House of Sand and Fog, Q &A columns like this one on creating dialogue by writer and writing teacher David Freeman, as well as general articles on writing like this one by writer Marilyn Beker. A tad heavy on writing for movies and television, but there's still plenty here to explore for "regular" writers, too.
*Blogger seems to be having trouble with picture posting today, so at the moment there's no picture or banner.
