Metallic- we did this 7 years ago- same Benjamin Moore metropolis on one wall and same golden color (mushroom something) on the other three. The ceiling was done in metallic steel /silver. i love the metallic ceiling! It reflects the room like having a lake on the ceiling!
DIY Upholstered Wall Hangings 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. This would be great for our hallway.
Add a little bit of a modern, chic look to your room by doing the ceiling in a light, simple wallpaper! How about spray painting adhesive add lace then.....spray paint a color or colors...then remove lace gently? LOVE this .... Jax
