Today I am sharing how I did it. My explanation is not the only way- it is just be the way that works for me!
It is often difficult (not to mention expensive) to find curtain rods that are long enough to span the length of a room. So, in my constant attempts to keep costs down, here is how I go about hanging drapes along an entire wall.
I use electrical conduit (which cost about $2 for a 10ft piece). . .
and curtain rod brackets (which are sold separate from curtain rods in most stores).
My first step is measuring the length of the wall. Then I use my jigsaw (with a metal cutting blade) and cut my conduit to be just a tad shorter than my wall length. You can also use a chop saw with a metal blade or certain hack (hand) saws.
(the blade on the bottom with the finer teeth is for metal)
(after I cut the conduit)
Then I screw my brackets into the wall at the desired height and put the rod in place.
TA-DA! You may want to add a bracket to the center of the conduit depending on the length of your wall to prevent sagging. Conduit comes in 10ft lengths, so if your wall is longer than that, you will have to buy a coupler (which is basically a piece of metal that will allow you to add another length of rod to the end of your 10ft piece).
(below is a coupler- you tighten the screws to keep the rods in place)
And that's how I hang curtains from wall to wall!
PS- If you are going for a more polished look and want to add a faux cornice board like I did in my master bedroom all you have to do is:
1. Cover a 1X4 with fabric using a staple gun and
2. Use "L" brackets (like the one below) to attach the board to the ceiling.
I hope this will help you to create your own wall full of fabric!
