After deciding how long I want the coat, it being a compromise between being too long and tripping over it all the time (as I did with my Mk I - hell that was too long!) and ending up too short, I pin the hemline I want to have.
I then press it along the hem to define the edge I will work to.
While I was researching The Competition’s Efforts, I noticed a couple of pictures showed people wearing their Tennant coats held open, to show the internal pockets.

When they did this, the lining was hanging like a big bag and sagging badly in the middle (see left). I wanted to try and prevent this, so I sewed the lining’s vertical seam allowance to the seam allowance down the insides of the coat to support and secure it. I did this from around 6 inches below the armpit to 18 inches from the hem. This is a bit unconventional - I’m sure you aren’t supposed to do this, but it has also stabilized the position of the lining around the hem area, which I then found much easy to work with.
The hem is then laid out flat and I cut the lining level with the seam allowance of the coat hem (see right). At this point I need to check the circumference of the the lining and the coat match. If there is any extra, I just slightly take the vertical lining seam in a bit.
