Progress during the week was kyboshed by that little thing that we refer to as work. Well, those of us who haven't retired yet...
But this weekend was a bit more productive.
Cut and PVA-ing rockwool for a couple of corners:


One corner frame with rockwool stuffed:


And one finished frame:


Not fully installed yet but you get the idea.
2 corners done, 2 just need stuffing and cara-ing.

And then that's the easy bit done...
