NEED HELP LADIES! I can't for the LIFE of me understand why these freaking feathers are so expensive. I'm trying to plan my engagement party and I need some beautiful feathers to create center pieces. I will need about 420 plumes and about 160 drabs....

I'm wanting to make the ostrich-feather eiffel tower centerpieces, and was wondering where you have/ haven't had luck buying ostrich feathers.
