CLICK ON THE IMAGES TO ENLARGE AND THEN CLICK IT AGAIN (on the new page) TO MAKE IT FULL SIZE^The above pattern gave me the most trouble because the snail and blue tulip icons were longer than the other (more rounded) ones. So it was a bit tricky to arrange them, but I finally got it worked out. Not sure if blue tulips actually exist, but they were initially pink and there became too much pink with the bird in there as well. My stripes pattern was created for this design, but it can go with the pattern below because of the light purple, blue and yellow is the same (maybe a little lighter).
^This pattern is my favorite because of the whales. :) (I named this pattern "It's Raining Whales!") Compared to the pattern above, I threw this one together in about 15 minutes because all the icons had a similar elongated shape. The complementary polka dot pattern can work with this design as well as the one above because of the shared colors.
For both of the images, the single main pattern is on top, the complementary pattern is in the middle, and on the bottom is the main pattern repeated in a square.
