I made these backgrounds so many years ago I actually forgot about them. See those backgrounds with the really old versions of Mara's pets? That's how long it's been since I made these.
You will (obviously) need to tile/repeat them in order for them to work properly on your website. Please do not hotlink! Instead, click the thumbnail of the image you'd like to use, download the actual background image to your computer, upload it elsewhere and link from there.
