To install the plywood panels:
*If you don’t want to screw them in, and would rather them sit inside the frame like the white ones do*: You’ll have to take the thickness of your plywood into consideration. As well as how close you’re trimming the wood, to ensure they’ll fit. Honestly, this was way more work than Zach or I wanted to take on, and I actually really like the dimension the plywood gives when it’s attached to the back versus inset.
