This looks awesome, @cmplxty. So this is why I tend to find you around my DIY posts, a fellow woodworker. I might need to do something like this to keep off the mess I make while working. I've taking my mom's sewing table as hostage for my tools. Did you get this as a plan or did you plan it yourself?
Also, I see some good tools around. There goes my tool envy. You know the good kind.
About the mistake, I like the idea of having the chance to fix something that went wrong. It certainly helps get your mind working outside of the box (see what I did there).
