But I recently realized a solution... floating shelves! Since we can't fit any more standing shelves or other furniture pieces in any of our rooms, it's time to start utilizing the walls. I've had the idea for awhile but never bit the bullet because these kinds of shelves are so dang expensive. And yes, I know that we (i.e. my handy husband) could just make some if we really wanted to, but there's plenty of other projects on our/his plate right now and frankly I didn't want to wait six months for them (no offense, honey).
Additionally, I had extra incentive thanks to $50 in Lowe's gift cards from Christmas (thanks, Mom & Dad!). So, after much deliberation and multiple trips to Lowe's, I finally decided on four allen + roth shelves (two 18" and two 24") for our living room wall. Even with the gift card, I still ended up spending about $60.
Don't mind the lamp sitting on the floor in the corner;
