Continue adding pieces in this manner. The last piece is again a bit tricky, you have to sort of bend the first piece towards yourself and slip the back piece of the eighth parallelogram around it. Once the star is completed, it can be tweaked by pushing in some of the pieces to make a tighter fit. The traditional color combination for these pinwheels is two contrasting colors, as seen above. Some unexpected results can be achieved with wallpaper samples by using border pieces or stripes.
Some samples have a border edge, so the center of the star is different from the points.
Also, some patterns can be cut so the design is folded along the center, creating finished stars with different patterns on the front and back. Both sides of one such star are shown below. Wallpaper sample books are a great source of paper for origami. The sample papers work well for pinwheels, boxes, and simple folds. They are too heavy to be used for origami animals or designs with small, precise folds.
