I did buy another $40 worth of Elfa components to round out the space (like the closet rod, another easy hang standard and track) but that was well worth it! And all said, we got all the original shelving for free courtesy of the previous owner. Those birch decor Fascia are $20 each and there are 7 of them here! The shelves were $12 each and again there are 7 of them here!
So we basically spent $40 and ended up with a $350 shelving system in our office closet. And thankfully, Elfa is a relatively easy system to install (it's like 7 holes in the wall, although that proved to be frustrating even for us because we own such a weak drill). But it is still much easier than installing wood shelves! Plus, it's easy to move around if I ever want to reconfigure the space! It's pluses all around! I'm so excited that I'm using way too many exclamation points!
And I did just place a few things on the shelves to demonstrate how awesome the space is. But I've since reshuffled the items as I saw fit. :) Oh happy, happy day!
