The tree picture is a black and white gif (2-color gif), so if you want to color them with a graphic software, you will have to change it (for example in Paint Shop Pro you should choose Colors from the menubar, then Increase color depth and finally 16 million colors) and save again as bmp or any format you would like.
Follow the instructions on the image, cut along solid lines and fold in half along the dashed line, then paste each left half with the right half of another tree. Good luck, and enjoy yourself!
| OK, now get me the black and white tree | No the colored one, please! (Are you sure? How much ink will it cost you?) |
