I found a nifty place where you can make your own font for free. It's very easy. You download a simple template and fill in the boxes, then scan it and upload it. They convert it to a font you then download and can install like any other font. It's hard to write by hand even with a Wacom tablet. I struggled with the print on the Valentine.
If I'd known it was really going to work I'd have tried harder with my handwriting.
