As requested by @cactus cowboy: A set of fourteen different seamlessly tileable patterns (see original file to get the full set, which works in Inkscape). 11 of those were made for use in a calendar. The rain pattern has a grey background in Inkscape, no idea why it doesn't show up in Firefox.All patterns are editable in Inkscape, so you can change the colors to your liking. Some are based upon other Open Clipart and PD graphics.
