UPDATE- a little further along with this after a break whilst on holiday. Just in the process of a house move aswell so unfortunately it has taken a back seat. I've got the French contingent still in their box at present as I'm running out of bench space until I get the Coldstreamers finished but hoping to get them started in the near future. Apologies for poor quality of pics taken off my phone.
Absolutely stunning
To answer your earlier question, re: Did we stay at the farm ? No , we stayed at the "1815" Hotel just along the road, and it's actually on what was Wellington's front line.
Look out the bedroom window, and La Haye Sainte farm is right in front of you. Sent shivers up my spine. The Hougoumont apartment is under Landmark Trust, and although not expensive (self-catering), is booked up until God knows when.
