I have loads from John Lewis. In my experience they donโt shrink or fade and last for years. https://www.johnlewis.com/john-lewis-supima-cotton-jersey-crew-neck-t-shirt/navy/p6030384
Iโve been hunting for a radar app as good as Dark Sky ever since it was discontinued, but not found one so far. Currently Iโm using Ventusky (on Apple) because it provides a lot more detail than rain radar (wind gusts, air pressure etc).
I'm guessing it will take time for a Cambridge community to become established as the "main one". I found a Cambridge UK community on kbin.social, posted a Hello, then tumbleweed. I'm north Cambridge btw!
I wondered if it might be something to do with the real name policy on Facebook. Instagram is closer to Twitter in not having such a policy.
