Here are some ideas for ways to use extra duck or chicken feathers.
I have been collecting the clean duck feathers that I find on the ground over the last year and recently decided to make some ornaments. I bought glass ornaments and just put the feathers inside through the top opening. I bought some cute ribbon and attached this to the top of the ornament. Super simple to make and very cute. They will make great decorations or gifts.
Here are a few other ideas I found online but haven't tried...
