I used a glass canister (with a lid) and left off the flowers. For Christmas I changed to Peeps snowmen and Christmas trees and Christmas M & M's. (I put a plastic cup in the center of the canister to hold the Peeps in place. I filled the cup with seasonal candies...candy corn or M & M's.)
Bats -- I've done this for the past two years. The bats can be stored flat to be used for the following year. It is definitely creepy and everyone loves them. You can also do this around your door outside or on railings, etc.
