from triangle to square and back to triangle

 3 quilt tops of various sizes later but I"m still stuck on this color palette. 

 Here's the next version I've been playing around with a bit.

Tried to make some fishes for fun.   Here's the conversation with my 3 yr old.

Me - "Hey Olive, what is this?"
O - "A diamond"
Me - "Are you sure?  What is it?"  (move it like a fish swimming in the water up and down)
O - "A pillow!"
Me - "How about now?  I added an eyeball.  What is it?"
O - "A one eyeballed scary monster!"

Me - I give up.
