For this project, I wanted to create a crisp pattern that would like nice on a backpack or maybe a skirt. I went through a few ideas, including rain clouds and flower patterns, before deciding on drawing mountain ranges. I have always loved how mountains are graphically represented; the clean lines and clever usage of color blocking to create dimension are just very pleasant to look at for me. With that in mind, I decided to create something similar with a fun color palette.

 
As far as coding goes, this was a bit of a challenge for me since I am still trying to fully understand for-loops and creating my own functions. I tried to incorporate functions into my code instead of drawing the shapes in the loops to practice these skills some more (and so that I could relate all of the mountain’s shape points to one primary point using arithmetic and not having the loop mess with these relationships).
