For this project I started with a flower initially to create a wall paper pattern. I started to modify the form from there and transformed the petals into irregular petal shapes. I have populated them by giving 6 petals a center. I had to scale the petal sizes down because they were too big initially. I have used the color to give random variation through out the wall paper. I have used for loop and random variable for the color lies inside of the loop. After the placement of the petals, it needed extra color of form to contrast with. I decided to put white transparent thin lines to give emphasis on the petals and contrast through out whole wall paper pattern.
