First, I measured the outer dimensions of the KALLAX unit and cut the wood panels accordingly. For the top and bottom panels, be sure to add a margin to overlap the additional two side wood panels. Then sand the panels down, especially the rough edges.
I then measured the dimensions of the cube. A thin plywood was cut to create an overlay for the shelves. It’s a nice touch to tie in with the new look.
Next, I stained the pieces with wood stain. And let them dry thoroughly.
After that, I glued on the wood panels on the outside of the KALLAX. For added security, I added some screws piercing the wood through to the KALLAX.
