Watching an old episode, I suddenly noticed that each of the 3 sides of the TARDIS bears an architrave feature running down the middle of the panel, mirroring the door-stop architrave on the doors.

Bum! A quick visit to hardware for what I hope is my last purchase of timber for this project, and away. I agonised over whether to make the thickness 8mm so as to match the first step of the horizontal skirting under the lightbox, or to step it to bring it in level with the third ‘step’.

At this late stage, I decided to do the least amount of mucking around, so went for the flat design. I noticed in random viewings of the Baker (2), Pertwee and Hartnell Tardises that both cases are true, so it was a coin toss anyway!
