I was “taught” cursive starting from grade 3 and for many years my handwriting looked like Charlie Brown’s. It was a very discouraging experience. What didn’t help was my logical brain arguing that cursive didn’t make sense (why does the capital Q look like a 2? Why not close the loop?? And why does the G look like…well, whatever it looks like - certainly not a G).
When I was 13 or 14, my mum taught me the method she’d learned in England, which she referred to as italic. Being more angular and less loopy (and no letters disguised as numbers) made it a lot easier to learn. Today’s handwriting is a mix of that and the block lettering I learned in drafting class. Best of all, it’s legible!
