An interesting design, and what a treasure to have. Looks like it is in great condition.
When I look between the two, they look different.....
The suggested link shows the feathers with individual pieces and background showing between.
Whereas this one has a solid feather on the background.
I won't say this is not Princess Feather ... but to me that is a big difference.
However, quilt patterns often do have many different variations to them, too.
