Managed to make a little bit of progress on the coop before it started raining again. Got 2 windows and 2 arrow slits cut out. I used a soldering gun for this. It's great fun.
You could see the wheels in our kitty's head turning as she was calculating jumping into the windows of this box she could play in.
Between episodes of rain, I'll run out and cut out as much as I can today. I'd really like to get my Tracer out and project the stones onto the wall so I carve them out with the soldering iron too. Hoping it doesn't rain this evening, otherwise will probably have to wait until tomorrow night.
