After unsuccessfully searching for a key rack/sunglasses etc holder we stumbled upon the Svartsjon towel rack in our local Ikea. We noticed it fit almost perfectly on the front of the spice rack, which looked great for storing sunglasses. The coat rack is about 1/8″ longer on each end but we think it works and looks great.
Simply assemble the spice rack. Then place the coat hooks on the front and mark spots to drill holes for the screws. I found a couple screws in the garage and attached the coat hook to the spice rack.
