Yarn from nettles sounds interesting, lixy. We don’t actually get nettles but there are probably similar things here. I went to Venice for the first time in 2019 and I agree, it is a wonderful, wonderful place. The Great Wall of China is pretty steep, depending where you go, but amazing. I have been there a couple of times to different parts but now I wouldn’t be comfortable going to China or Russia, for that matter. Never seen the Northern lights and that would be good but I have seen the Southern ones in Tasmania when we lived there and perhaps they are similar. I didn’t know what they were, thought it was something wrong with the atmosphere or a UFO or something. A friend told me , I hadn’t realised you could see them there.
