My guest post on creating cover art is up at Kristen Lamb's blog. Huzzah! I was so worried because I had no idea if Kristen ever got my files.
Now don't make me look bad. Go over there and ask me questions--or at least make funny faces.
This particular post was particularly important to me because it's the one thing I can talk about with expertise. Whether you're creating your own art or looking for a designer, I hope you find it useful.
