Stay At Home Robin - Step #3

I needed a little break from strip piecing bazillions of blocks, and got out my Stay At Home Robin project.  To read about my fabric and theme choices, and to see my first two steps - click here.

I decided to try another circle construction method recommended to me by Michelle. To see the tutorial website she sent me - click here.
I prepared a few pieces of fusible interfacing and decided to try some half circle shapes...from where do these weird ideas come?
Anyway, here is my SAHR with step #3 added.  I am enjoying the process of following any ideas that pop into my mind and not worrying about the end result.  After I finish constructing the step and add it on to the previous parts, I step back, look at the whole, and say "what the....?????" LOL
