Three IKEA Benno CD/DVD shelves side by side.
Question: What's wrong ? Answer: all intermediate vertical panels come twice.
Find it ugly, or space-wasting, or both ? Here is how to fix the issue.
Step 1: Buy the Shelves
In our case, we will mount three Benno shelves... So we will have to buy three packs!
In the end, two side panel will remain unused. (We'll certainly find some cool Instructable to use them.)
