The last high rise I lived in had this long, white entryway with high ceilings. The wall needed some art to create interest when you walked into the space. I wanted something oversized to cover the wall, but that didn't cost a fortune. I ended up covering three 4'x8' pink foam insulation boards from Home Depot in a large repeat, silk, damask fabric, which ended up being much less than any art I would have found in that size. I just stretched the fabric around each board and staple gunned it to the back. You could also use spray glue for this application. Let me know what you think about this project, or if you have tried something similar to this before.
