I saw this pie crust and started thinking about creating a Granny Square in C R O C H E T. 
Any artist who works with color probably understands what color wheels are, their importance and use. Color wheels are used in just about every industry like paint, fashion as well as crafts. Not being trained in the use of color wheels, I am color challenged every time! SO, I compensate in other ways with what I have.
I put my creative hat on to choose thread colors for the flowers that would best complement the crochet chain of brown and green.
Diving into my bins of thread balls, I set a bunch of colors on top of a white surface in a circle, laid the crocheted chain across them and what-do-you-know I created my own color wheel! Funny thing the right colors just popped out!
