(Generally, not just evenings)
Crafting - knitting, crochet mostly. I'm also trying to learn Tunisian crochet and tatting from YouTube videos.
Sketching - both with actual pencils and paper, and with a digital pen and Autodesk sketchbook on my 10" tablet.
Playing games on my Xbox 360, mostly jewel type games, or board games like chess, draughts etc. against the computer. I'm crap; the computer always wins. 😅
I try to play recorder; I have all types, sopranino, descant, treble, bass. I'm not very good, but enjoy playing anyway.
Reading, both paper books and ebooks.
Writing in my diary. It's the type where I write about my day, my thoughts etc., not an appointments/ to do type. It probably makes for very dull reading, but I find it helpful and calming.
Listening to music I love, which is usually combined with something else, like knitting etc.
Watching TV, films etc, again, usually while crafting. We subscribe to Prime, and also find plenty to watch on BBC iPlayer, All4, My5, Itv hub etc.
Doing puzzles on my tablet like Classic Word (like Scrabble), Wordle etc.
General internet browsing.
I never feel bored, there's too much to do and think!
