Hi Shelley,
Here is a picture of my glass storage. The wooden boxes still need to be painted white!
If anyone is considering using this type of setup, I recommend you measure the width of the plastic pipes and decide how many you want to use so that you can build your case to the right width. The piece of wood that you can see in the top case is to compensate for a measurement error and makes everything stay in place! I learned from my mistake and did better with the bottom one. The same method should also be applied for the height measurement.
Hope this is helpful.
