Do you ever raise and lower your dining room blinds? If not, I'd just keep those windows without blinds and focus on blinds for the great room. (Do you use blinds in the great room either?)

Thanks. We rarely raise the blinds in the dining room, but we do raise and lower the blinds in the great room for privacy.

they can be different.

just make certain they compliment the space you are using them in.

If the windows are on the same side of the house they should look the same from the outside
