More information is needed---size of windows, privacy and light control needs, entire house or two rooms? formal? casual? modern? mid century modern? traditional? Country?

I'd like to find the best deals on " no tool " blinds for my new house. Room darkening, casual, for the whole house.

Call this a thought experiment.

Maybe you have 2-3 different sizes of windows. Pick a size that could stand in for most windows. Call it a project window. For this project window, go to Lowes.com, homedepot.com, or your choice. Collect costs for:

Set of curtains

Set of blackout curtains

Pulldown shade-blackout

Roman shade-blackout

Venetian blinds

You have some treatment options

Figure out each window in house:

Anything worth seeing out this window? View

Can anyone see below your head through this window? Privacy

Will window wake you up? Light

Wanna hang out in room that has this window? Ambience

Each window may have one or more characteristics

Tried to avoid overthinking while writing this. Partial success.

Maybe make rough floor plan with window locations. Two columns by each window. One for characteristics. Another for options.
