So first I tried to hand piece the center compass. Not a success. I couldn't make my stitches invisible. So I decided to English Paper Piece (EPP). This went better. Here are my compasses.
I can see my stitching, yikes!
But the EPP turned out better, to me.
The next step is the compass ring. See if I can get to that tomorrow.
Thanks to Esther and everyone who so selflessly gives expert advice.
