That's really interesting, @Path! 1px wide! Wow....
@Kerry, I created the gradient in Photoshop. Sorry if you don't have that. I'm no pro and it always takes me a while to do tinker in Photoshop. I created the gradient because I didn't like the way it looked when it was tiled.
See, when the image goes from one color to the next and stops there, then the two colors "bump" into one another when tiled. But when you create a gradient that returns to the first/top color, then the tiling flows seamlessly.
E.G., red to white gradient. If you create a background that goes from red to white and stop, the white will bump up against the red when tiled. But if you go red to white to red in your background image, then the two reds will bump up against one another and you won't see the tiling!
My image was 2000x3500 JPEG. However, it's a small file size because I can adjust the file size via quality in Photoshop when saving.
Hey, it's Thanksgiving! So if you want, I can create a background for you!!! You can contact me through my blog :)
