I was concerned that we had made the sides appear too thick with the three-inch mitered returns. Three inch returns ensured a lot more structural integrity against racking, but seemed massive next to glass doors with thin frames.
Once the doors were installed, however, I was really happy with the look. I think I'll do smaller returns next time, but for this project the proportions don't seem too heavy.
Also had some fun prepping stock for another workbench.
