If you don't have a lot of room to mount curtain rods around your window frame, or you just want a different look, grab a set of saddle-grade leather straps. They're easily screwed into the wall, lightweight and look good even with a curtain hanging from them.
You can get heavy-duty leather straps at home improvement stores, but you might want to hit your local outdoors or sporting goods store first. The ones used above are Hermann Oak Harness Straps, available from Outfitters Supply. Combined with some simple wood screws, they make great curtain rods, and while swapping out the curtains requires unscrewing one end, they work well, even with these semi-thick linen curtains.
Best of all, they're cheaper than hardware, especially if you have wide windows or windows with narrow edges. Hit the link below to see more photos of the room above.
