Help Covering HIDEOUS Walls for a Reception

What about a roll of butcher paper that can be taper or stapled at the top of the wall? if it's thick enough to cover the drawings on the walls you could choose a light color to make the room look bigger. i'm not sure where to buy this type of thing, but churches and schools always have these rolls for making posters. that's where i've seen it before.

a more expensive option that would look slightly better is to do the same with fabric - i would choose a satin - and keep it up with push pins in the wall. I haven't tried this before so i'm not certain it would stay up. best try it out before committing to a plan. good luck.

Could you hang fabric with some Command hooks? Those are removable and won't damage the walls. Many venues that don't allow nails/screws allow the Command hooks.

Command hooks. Come right off the wall when your done. Buy cheap curtain rods and drape material.

I found this link that might help you. It uses twine, glue, and thumb tacks. It should be pretty cheap, but I'd still do butcher paper under it. I think you could tape it instead of using tacks, too. http://mymommatoldme.com/diy-crafts/diy-crepe-paper-photo-backdrop

How about gift wrap? The nice thing about your walls is they're not too high. I think with the right color or design it could be really pretty.
