Thanks for looking at it.
Here is my process:
I first thought about how to make a six-pointed object.
I made a vertical line, copied it, pasted it in place and rotated the copy 120 degrees since it rotates by its center point.
I then copied the copy, pasted it in place and flipped it horizontally.
This gave me a basic stick figure flake. I locked that layer and used it as a guide.
I then used the pen tool to make one arm of a flake until I liked the design.
I copied one arm, pasted it in place, flipped it vertically, and then use the alignment tools so the arms were end to end.
I then grouped the two arms, copied the group, pasted in place and rotated the copy 120 degrees.
I coped the copy, pasted in place and flipped that second copy horizontally.
I liked how the bases of the six arms interact with the others in this design. I think this is my third design. I tried to not take too much time when creating one arm to try to make it somewhat random and fresh. I wanted to just create some points and edges where the shape widened as it neared the base.
I only used a 6" x 6" document. Using bigger dimensions would have meant a more complex design. I was worried that I may over-think things. I wanted to make a quick design to try to keep the design spontaneous. I wasn't worried about making it realistic.
I do like the variety of designs posted. Lots of different approaches to this challenge.
