Are you going really wide? There should be studs right over or next to your window trim. There may also be another (probably not symmetrical) within 16". It's best to hang rods in studs instead of using anchors. If you *must* use anchors there's a kind that looks kind of like a screw on the outside, it's plastic but it has coarse threads. They don't recess into the wall though. But they're easy to knock though and mud over if you ever change the rod position. They come in different sizes to use with different sized screws. They also come in metal for heavier-duty jobs.

Threeapples, you are going to live in that beautiful house for a very long time, and over the course of years things will need to be fixed, touched up, repainted, repotted, rehung, new pads for the rugs, Christmas trees put up, lights changed, new artwork hung and old holes patched and painted....the list is endless. You should start now, while your house is new, interviewing handymen until you find one who is meticulous and versatile. Keep a running list that he can do and pay him hourly. A good handyperson will also walk your property and keep an eye out for maintenance issues that can be repaired before they do damage, things you might never notice. This relationship will help keep your home in tip top order, will save you countless hours of trying to find many different professionals to do each job (he will know people who can do work if it's out of his scope), and give your husband weekends free to enjoy the home instead of maintain it. Our Handy Guy has every tool and can do just about anything, and if he can't do it he can find someone who can. Our first five years living here was difficult because I felt the house owned us. Now I email him a list, he gets what he needs, comes down and takes care of everything from pressure washing in the spring to replacing faucet parts. Ask everyone for recommendations, but especially realtors who deal in high value propertied, as they will often have the name of a person who does ready work on their listings.

You can buy mounting brackets that extend out 4.5 inches, but it sounds like you have a rod and brackets that you plan to use. Can you post photos of them so that we can see what you are working with? A double rod is used for placing sheers under a drape. It isn't going to help you with not having enough drapery panels.

btydrvn......really was not meaning it to be rude....was under the impression From your post that you thought Or misunderstood that we where adding shades over shades...the silhouette shades are already installed but you can see the plastic silhouette cover very unappealing...the drapes are stationary and will not be opened and closed....so to add a more sophisticated look we are covering that plastic cover with a woven waterfall shade than adding the beautiful pinch pleated drapes...in image the automated roller shade is hidden by the waterfall valance and up as high as the rod to give a cohesive finished look and allows the rod to go up higher with out a gap between top of windows and rod...will not be a heavy look with light waterfall and linen drapes..
