Re: Room Dividers
You are only limited by your imagination. I would recommend looking at architectural details in home improvement magazines and websites, find something you like, then replicate it in your home.
Arches aren't overly difficult to build, particularly if they're not structural. I would also suggest the inclusion of some columns to support the arch, and possible a half wall between the arch and the connecting walls.
Another option would be to do the half wall and columns with no arch, which will keep the space open and airy, yet still define two unique areas.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
