We painted Ikea TRABY shelves
and hanged them on the wall.
This project required a lot of customizing and preparation. Although I'm very happy with how it came out, I would recommend to do something like this ONLY if you have a workshop outside of home: I painted and dried these shelves in my living room - very messy process that lasted for a couple of weeks.
Step 1: Shelves - Preparation
a) shelves were painted or stained before assembly
b) shelves were re-enforced with wood boards in order to hold the weight
Step 2: Walls - Preparation
a) the wall was checked for studs, so the shelves can be attached to studs for sturdiness and reliability
b) the wall was marked with grid lines to arrange shelves in this order
Step 3: Shelves - Mounting
the shelves were screwed directly into wall studs (they use the same technique for kitchen cabinets mounting)
