Nifty jig you made there, smart that it can be used on both sides! - And I like even better with all the router marks on it.
I genuinely hope that we all save offcuts for situations like this. Often way quicker to reach for the box of offcuts rather than cut new pieces.
Also looking throught that box I am reminded of all the projects I have made, the errors, the victories, the redesigns, the jigs, the different timbers I have used etc. It is like a small storyline of my hobby through the years, worthy of being remembered
