My issue is that I don't like traditional feathers.
So I don't make them.
Therefore, when I think I might want to make some, I have no experience and they look like $#@&.
I spent some time trying to work out the flow.
It helps me to identify the spot on the inside curve where I need a "circle" to wrap the opposite direction feathers around.
When I was stitching it, everything felt smooth and amazing. I tried to focus on ending the feathers in the same location to make heart shapes.
On close inspection, 30% of those feathers are still a little wonky. And my effort to make a "stem" spine on the right just simply looks bad.
