The best part of this project? It cost absolutely NOTHING except our labor! Hubby had a bunch of scrap plywood in his shed (plus he has like 1,000 screws, nails bolts, etc. in there). I had white paint and primer left over from former projects that I used. While I wasn't too concerned how "professional" it looked because it is inside the pantry I did cover all exposed screw heads with some air dry clay before painting so it would look more "finished". Also I was finally able to utilize a small collection of vintage glass spice bottles that had been stored away for years that had come from my husband's family.
If you are handy (or have someone who is to help) it is not a particularly difficult project. It took my husband about 2 weeks to build it working in his spare time. Honestly it took me longer to paint it than it took to build it! For the cost of plywood and some paint (and elbow grease) you can have a great way to organize and add more space to your pantry.
