We needed to update our shelving unit in our pantry style cabinet. We had been dealing with something from the early 90's and it definitely wasn't helpful. We couldn't pull it out and it was experiencing sagging. My husband built rolling shelves from leftover wood in the garage and some tracks from Lowe's. Then I lined them with leftover wallpaper from a previous project. The entire project cost around $32.00 because we used wood we already had laying around. Check out our blog for more information.
