My handwriting is about as bad as it gets. While this comes in handy for writing prescriptions (pharmacists don’t know how to deal with legible ones) I’d really like to improve it for letter writing, etc.
Has anyone here undertaken such a task? Any suggestions? Online resources? Thanks.
A computer with word processing software, and a good printer. 
The book Drawing on the Right Side of the Brain has a section on improving handwriting. It’s by Betty Edwards and published by Tarcher.
Learn a little calligraphy. It changes your writing style and method substantially. You’ll gain a different perspective on shaping and placement of letters.
My handwriting had always been appalling, but just a little calligraphy practice improved it enormously. I can’t write well enough to address a wedding invitation, but my writing is definitely legible now.
I have had the same experience. I took up calligraphy and collecting fountain pens and it helped lots.
Actually, I did get a teach-yourself Italic calligraphy book a while back and learned how to write in that hand. I can still do it pretty well, but it’s very slow, I have to use a special pen and hold the paper at a very weird angle (I’m a lefty). Also, when I write that way, my legal signature does not look like my signature! What I need to do is have my writing look like my own handwriting, but neater and more open.
I found one web tutorial which boiled down to writing with your whole hand and arm rather than just your fingers. I truly am a finger writer, so I intend to practice some whole arm movement and hope that some of that translates into my handwriting.
Oh, well that’s your problem! 
But, really, I’m left-handed, as well, and I’ve gotten a lot of, “Hey, your handwriting is pretty good for a lefty!” I guess they expect it to be illegible if you’re left-handed.
I’ve noticed, though, that I don’t write like most left-handed people do. You normally see lefties with their hands curved around like Captain Hook, and they sort of scrawl their symbols onto the paper. I actually hold my pencil like a right-handed person does, and I don’t turn my paper sideways (another common left-handed trick).
Here’s a good website I found. Good luck!
You just write in the new style . . . leave your signature the old way.
Yes, it does take longer. That’s part of the reason it works–it slows you down. Just adapt it to your handwriting using a regular pen.
Remember, too, that slick-slidey ballpoint pens are terrible for penmanship.

I work for a large group of doctors and can tell you the biggest problem is that they’re always in a hurry. Your handwriting is important. Slow down a bit!
