OK, now everything lines up.. so its time to put that quarter circle on..dont be afraid now, this is not hard...
First, you need to sew a stablizing stay stitch along the inside curve of the fan, a scant 1/4 inch from the edge...
I tried to sew this curve seam without clipping and it was too tight, so, clip.
Only clip to within a few threads of the stay stitching.. dont clip through it..
And I only clipped once on each fan piece.. in the middle, so, eight clips...
Now, pin them together.. you only need five pins..
First, fold the quarter circle in half and mark the center by finger pressing a fold.. line up the fold with the center seam on the fan and put in a pin.
Then line up each edge and put a pin in each one..
Now, ease between the center pin and one side and place one pin in the middle of this section.. do the same with the other edge..and you are ready to sew.
