I thought everyone here would delight in this amazing page that describes how sorting and processing feathers was a social event in old Poland.
Also, it discusses a bit out HOW to process feathers for use (you strip them, sort them) and what they were made into. (the best feathers into blankets and pillows, the chicken feathers and lesser quality into mattress pads).
Enjoy!
