Need some creative ideas, ladies! What to do with paper ostrich feathers?

The only thing I can think of at this moment is gluing them to a streamer, or garland and hanging them from your head table upside down in front of the skirting. Have the straight part on the top edge of the table facing the guests. And I wish I had a picture cause it doesn't look as bad as it sounds in my mind..lol

Maybe include them in your centerpieces? or add one or two to each bouquet? otherwise I would attach them to a large piece of fabric or a craft board and hang it behind the gift or cake table?

Could you fan several of them to make a circle under a vase centerpiece to go on?

You could use them as as place cards? Or Table numbers maybe?

They would make a good bottom to a centerpiece as @futuremrssullivan said. Or maybe string them at the end of the rows for aisle runners in your ceremony.
