Ok, I might as well go first: I wish I could draw. Not at the level where I could make photorealistic portraits, but I’ve always been envious of those who are able to scetch something together in a few minutes that perfectly captures what they want to convey. Sometimes words aren’t enough to express what I want to say, and for those situations I would love to have a simple drawing do the talking for me.
All kinds of things really although mostly they’re on my list to learn so I’ll have them one day. Tatting might be my main one for 2024.
(Edit: Forgot the “why”. Mostly because it’s come up twice lately here on Lemmy and I feel left out while other people are making pretty lace)
I do wish I could learn to draw a bit better, to play the piano, and to speak multiple languages. But realistically I don’t have that kind of time so have to go with things that are quicker to pick up!
