How to decorate my Banquet Hall without putting decorations on the wall?

Uplighting?

You can use uplighting. Different lights with different patterns to help cover up some of the blahness. Also, maybe use drapes to help too

Thanks guys here a 2 picture

My first thought was draping. with Christmas lights around the top - like this photo but around the walls.

Yeah, I agree with PPs...drapery and uplighting would make a world of difference.

I've seen on Pinterest where people used PVC pipe to build something for draping when the venue didn't allow anything on walls or ceiling. You could probably get some great ideas from there.

If you rent pipe and drape, it doesn't touch the wall, the people you rent it from install and remove it, and you can probably get them to add the icicle lights for you. Maybe add a little uplighting, and it will look amazing.

I don't understand renting a budget facility that requires the installation of white Christmas lights on the ceiling, PVC piping and yards and yards of fabric, and curtained off whatevers. If the ceiling is so important, rent a venue with a beautiful ceiling and let your guests enjoy it for about five minutes or so. If you can't pay for that, don't try to fix what can't be fixed without a lot of money.

Do you know how many times I, someone who remembers the decor of the last ten PERSONAL weddings I've attended (remember, I do decor for a living, and I look at everything -- down to the bathrooms), remember about the ceilings of reception venues at which I've been hosted? Nothing -- unless they're gorgeous/outstanding. If the ceilings are not vaulted, not tiled, not canvases for beautiful artwork, not glass, or don't have glistening chandeliers hanging from them, they don't register with me unless they are highlighted with DIY paraphernalia. Then I get it...these people are insecure with what they rented. They wanted something else, and all of that removable stuff is evidence of that desire. People know what PVC piping and inexpensive nylon fabric looks like, so why spend the money to disguise the obvious? Take the eye away from the ceiling.

Dim the lights and draw the eye down. Use uplighting, and that burst of color will start at the floor and stop before it reaches the ceiling. Focus on candles (real flame or the fake flames) and spend your money on beautiful, lush floral arrangements (DIY them if you think you can -- although I don't suggest it. I say that because I don't want this to sound like a plea to support your local florist. It isn't. It's just Design 101). Spend your money on some eye-catching sequined table runners or table cloths. Nothing grabs the eye more than glittering sequins, especially when the lighting is atmospheric, and using a sequined cloth on the sweetheart table or the cake table will cost you far less than all of the stuff you'd be purchasing to draw attention to a basic, nondescript ceiling.

Remember, all of that stuff you think you want to hang on the ceiling isn't a quick, easy, or cheap job. You have to pay someone (or coerce a friend or four) to stand on ladders and hang all of this stuff up. Then, at the end of the reception, you're free to join them as they pull them all down -- possibly inebriated -- while standing on a ladder.

Never draw attention to what you want to disguise. Spend the money you would have spent on the piping, the fabric, the lights, and possibly, the labor, on decor that will be at or right below eye level. Add good food, good drink, and great entertainment and you're reception will be a massive hit.

Flowers, lots of flowers. I am not a fan of banquet halls because they feel like high school gyms or hotel conference rooms to me. To make up for the missing windows I think flowers brighten up the room.

I have the same dilemma, I'm using a community center. We'll be doing uplighting most defintely, and they've agreed to take out a couple of light bulbs to dim the room lights since there's doesn't have a dimmer.

Drapery and uplighting is definitely a good idea.

I also disagree with the idea of using drapery, especially if you're planning to DIY it. It's way more trouble than it's worth for a non-pro and it's insanely expensive to do it properly. Uplighting will help more than you'd think.

I would try to draw the eyes away from the walls with nicer centerpieces. You can rent them or get them for cheap on craigslist and local wedding facebook pages for brides. Candles in votives are cheap online and you can decorate them up yourself. Just make sure you are allowed to burn candles there.
