Anything remotely artistic.
I have always been bad at that
partly because my hand tends to shake a bit - hence I cannot draw/paint a line where I want it to go
I could never even get close to copying a picture or anything
or so I thought until I had a daughter and she wanted me to draw a giraffe
but it had to fit in a specific place
I found a book with a picture in it and - with her watching carefully - I managed to draw a small section at a time and end up with something very like the picture and sclaed to fit
I was amazed
still rubbish at painting close to edges and the slight shake means some always goes over!
