Prom

I am Junior class President at my school, which means that I am in charge of planning our prom. We have picked a garden theme, although we have no "title" yet. The colors we are using are blues, white, black, and silver. We have our main decorations and table decorations thought out, but we are not sure how to do the chairs. They are not especially pretty, so I would like to cover them some how. They are not folding chairs. We were wondering if there were any ideas on how to do them. Possibly using gossamer, but we are not big on tied bows. If anyone has any help for us we would really appreciate it!
Thanks!
