Feather crocheted and knotted

I will show you how to crochet and knot a feather from a cotton yarn, in this case, Catania.
Catania is a yarn twisted from four single threads, the single threads retain their twisted form even individually, which is important.
The whole thing is a labor of patience, but I think the result is worth seeing.
