Help a girl out
This desk didn’t come with instructions and I have the base done, but there’s extra shelving in the top. I’m not sure now to attach the “wall” of the shelf to the desk, and no there aren’t holes on the bottom. In the photo are the three types of screws I have left that I’m guessing is meant for the shelf portion of the desk but I have no clue how to attach them to the desk. Much thanks
