Every now and then I find myself completely stumped. This puzzle through me for a loop!

My daughter pinned this on Pinterest, and she was able to find the solution this puzzle. I stared & stared at it for a very long time, and eventually had to ask her for help. Even after she told me the answer I was stumped. She had to explain it to me!!

Take a look, and leave a comment with your guess at the answer. Tomorrow, I will share the solution with you.
