Yeah this is weird, I thought I was having dejavu....

Kim, you're right.

I can't figure out why each time I hit refresh I'm getting a different posting on the site right now. (Either this question, or the radiator discussion.)

Sorry about that! I was out the day that went up last time and didn't see it.

there are rods that mount only on one side so they can be used as a room divider. if you got one for each wall, you wouldn't have to deal with mounting anything in the corner...

hope that helps!

Didn't we see this question last week?

I think you should just move. Your problem isn't curtains... It's the windows. Double-hung aluminum window sashes on corners are vulgar replacements of what were originally iron casement windows. This type of cheap treatment to an Art Deco building is all over Manhattan.

Either a previous or current owner ripped out the originals and decided to replace them with what you have now for maintenance reasons. If you can find a picture of the building from when it was first constructed circa 1930- 1945, I'll bet my shorts it was an iron casement.

The reason for this is that construction technology had advanced at the time to allow for a corner lintel. Corner windows are actually expressions of this innovation, and the iron members of old casement windows had thin profiles, which allowed the corner window to look lighter than the heavy double-hungs, allowing more light into the space...

Go have a look at the apartment buildings with casement corners on Central Park West... Another great example of a building that originally had casements and now has many double-hung sash window replacements is a buff-brick apartment house right on the southeastern edge of Abingdon Square in the West Village, right where Bleecker starts. Not all of the windows have been replaced on this building.

Good luck.

Ikea sells a curved corner piece. I have the same exact type of window. I bought 1 straight piece and the curved and put finials on either end. It looks great.

zarinfabrics.com on the internets or go to the store on grand street in new york. they sell corner curtain hardware.

ikea has a curtain system that has a component that curves corners. http://www.ikea.com/webapp/wcs/stores/servlet/ProductDisplay?topcategoryId=15594&catalogId=10103&storeId=12&productId=47531&langId=-1&categoryId=15846&chosenPartNumber=70079368.
this is the component and if you look up kvartal in search, you can see the whole system.

I agree with Paul. The double hung vinyl clad sashes are plain ugly, and have been an unfortunate epidemic in NYC since the J-51 tax abatement in 1988. These monstrous fat mullioned brown numbers have forever changed the face of NYC. Thank you mayor Koch!

However, moving would be a bit extreme. I would do floor to ceiling drapes wall to wall because they would diguise the ugly window frames / radiator / awkward seperation. I would turn the corner and extend past the righthand window by about two feet.

I did this in my own apartment using standard Ikea double rods with just one drape - I needed the extra inches of the double rod to accomodate the the extension of my window sill / radiator. The result is a straight hanging drape without bulges and the illusion of widening the narrow end of the room. Bringing the eye up to the ceiling will also make your ceilings look taller. A modern effect that works well with the period of your building.

You can get corner curtain rods at Made of Metal where the rods are mitered so the connection is clean. You can also get another rod for the other window with the same finish, finials, etc.
