Here is the coloring page version of the dahlia pattern. You can now select exactly the colors (or patterns!) you want for each petals group of every flower. The two color pattern was already quite nice (I think), the multicolor pattern is even nicer. More colors adds happiness to the pattern. The not yet colored version is also a seamless pattern: you can save the picture, and then use it repeated (you can use image edition software like Gimp or Photoshop to resize the pattern). Of course for the pattern to be seamless, you need to use the same colors for the flowers that overlap on the borders.
