Eek, look after yourself Roof! Hope you make a swift recovery.
I normally enjoy these large ones to do gradually over a holiday period, but with everything going on this year I can't properly get into this one. I've done a section in the middle and a smattering of others, and I have the theme so hopefully at some point my head will clear of life chaos and it'll come together.
Thanks for all the hints provided so far, very useful in helping me make some more progress.
