Vendor for Tent Decor

Hi all,

I'm getting married in July at the Harbor Links in Port Washington, and the cocktail hour will be outside under their tent.

Does anyone know any vendors that do tent decor? I'm just looking for several chiffon drapes on the ceiling to dress up the tent a bit. (Picture below to see what I'm talking about) My florist already told us that he does not do this. Any suggestions?

Thanks :)
