(Insert strong expletive here.) That's r i d i c u l o u s pricing for the average budget. You could go "cheap" on the blinds -- use old fashioned pull down shades in dark black -- then you can add your black sheers or something else -- perhaps a cornice or shag valance (long sided valance) as well to soften the look. https://www.google.com/search?q=solid+black+old+fashioned+roll+down+shades&source=univ&tbm=shop&tbo=u&sa=X&ved=0ahUKEwieopLal-DbAhWJt1MKHROhDMMQsxgIJg&biw=1366&bih=628#spd=518285860030355824&spf=1529427046761

Bumping this because I don't think the solution I found will work. These are the initial rods I bought. It seems as if we must unscrew the rods from the wall if we need to remove the drapes. The Umbra twilight room darkening rods I found (pic below) might not be the best solution either. Lifting the rod out of its "nest" attached to the wall risks damaging the paint on the wall. Could someone please tell me what's the best way to hang blackout curtains?

Awesome room! I would have tried to find curtains of the Imperial and the Rebel Alliance emblems on them. The other idea would be to do one black curtain for behind Vader and one white behind the stormtrooper -- or just both plain black. Might be neat to paint the wall the TV is on a black or dark gray.

I spy a cute baby! As a toddler mom I definitely agree that blacking out more light is likely to result in your little one (and all of you) getting more sleep. On my own windows (which are a more typical setup) I've found a combination of blackout blinds plus blackout curtains gives the best results -- neither gets the whole job done, but in combination I can get the room super dark. I'm not sure you'll be able to get blinds or curtains to cover all of this, but if you cover as much as you can with each it should be a big improvement. Here's what I think I'd do: -Get three sets of exterior mount blackout blinds (I like the cellular kind, but for a very affordable option you might look at the Ikea Fridans) and mount them above each transom; buy them long enough that they can pull down to cover both the transom and windows below. This means for both the right and the left, when they're pulled down they'd cover some wall and some window. For the one on the right you'd have to stop the shade at the edge of the closet. -Mount a curtain rod above the blinds (making sure it projects far enough not to interfere with the exterior mound blinds) running the full length of the wall and put blackout curtains on it -For that little piece of window on top of the closet, I'd sit something in front of it (nice looking box?) to block the light.
