No sheers all you need a rod that allows the drapes to pass the shutters and close so no light gets in the sides so a french return rod is probably the best and it will need to be at least 6" on either side past the windows. As for color probably the same as the shutters or close to it in white . Pattered drapes always look a bit fussy to me and dictate wall color, bedding etc down the road

Funny, my friend has this floor plan, but went with the second floor option (bedroom, bathroom and bonus rooms) and made some ADA modifications to the master bathroom.

What floor plan???

Third paragraph, click on the word "Windows".

Takes you to virtual walk through of plan.

WOW missed that totally.

It would be much easier if you simply posted a photo of your room vs. asking people to click on a link. Many people don't like to click random links + it would be better to see the room in your home vs. you describing everything.

I have to agree with Dani. It would be much more helpful to see a photo of your guest room. That is especially true since you're asking for color advice for drapes. Would you be willing to add at least one photo showing bedding and area rug?

I agree with Patricia that solid drapes would be better. Since your walls, shutters and furniture are white, would you consider painting the walls a soft beige to pick up on the beige in the rug? It seems the furniture would show much better against a color. And drapes the same color as the walls would not close in the room. If so, I would find blackout drapes in a beige color similar to that in your rug, then match the paint to them. (I happen to be planning this in my home, after much discussion here on Houzz.)

Nice suggestion for rod from both Patricia and Think. Think's description matches what I've been advised to do in my living room where I want drapes to hang very neatly. And Flo recommended the pleat style below to make the drapes hang neatly. That may not work with blackout drapes due to thckness, and it may not even be the look you have in mind. Nevertheless, I'm sharing it, just in case you--or any followers--are interested.

I looked at the model of the house. There appears to be plenty of space on each side of the windows. If it were my house, I would run the track to cover the window wall. You will want some space at the ends to insert the carriers into the track. Covering the entire wall should allow for plenty of stackback space.
