It's a wonderful idea to display a banner to identify your party's theme. This banner can be hung outside the party room, or in the vicinity of the dj's table. Believe it or not, getting a custom vinyl banner for your event is not very expensive! An 18" x 54" banner (with a photo on it) is only $21.99 from Bannerz (which is a division of Shindigz). I ordered one (the theatre curtain design) for my daughter's Bat Mitzvah, and it turned out beautifully! When ordering, I asked them to email me a proof before printing (type this request in the "special instructions" box). I received my proof, made a few minor text sizing adjustments with the banner artist, and it turned out great. I personally like the photo banners, but if you have a camera-shy kid, there are tons of text banners with attractive designs in loads of different themes (safari, hollywood, western, luau, etc.). A custom banner is a great way to give that "wow" factor as guests enter your fabulous celebration!
