For me there's no cheaper or quicker way to give a room a new and fresh feeling but to move the furniture around a bit...
I love the intimicy of having the two sofas close together without a coffe table.
It works well for our family, but not so much for hosting bible study groups, etc... so I doubt I'll keep it very long. But with the woodstove just on the other side it's very cozy as long as we lit a fire in the evenings (or all day, when it's really cold).
This table is rarly used for eating, but very often for homework, playing games, drawing... I like to have an extra table in the livingroom.
The piano wall is still nearly the same.
As I type this I have my girl snuggling up to me, one of the boys is sitting across on the other sofa, reading... and three boys are outside. One just informed me there was a diaper to change...
