Ask HN: My hand writing sucks, what can I do about it?

When I was about 13 or 14, I abandoned pen and paper for a keyboard. As a result my handwriting is beyond awful - frequently I can barely read my own writing a few weeks later. I often get issues with the bank as my signatures don’t match, and frankly it’s just a bit embarrassing. I’m fairly certain that simply practicing the art regularly would improve things, but does anyone know of any guided drills, programs (digital or otherwise) or any iPad apps that would assist in this?
