YourFonts is a web-based service that turns your handwriting into a TrueType font for free. If you have a printer and scanner, nothing can stand between you and the awesomeness of your own script.
The handwriting-to-font process at Fontifier costs $9 per font you create. YourFonts has a software package for making personalized fonts that runs $49, but the web-based tool is entirely free.
The process is straightforward: download the provided PDF template, print it out, and fill in each number and letter blank with your own hand writing. When you’re done you upload the template back to YourFonts, preview it to make sure it looks like your own calligraphic gift to the world, and then download it as a monitor-friendly font. Additionally you can use the service without actually printing the PDF out and using a scanner—if you’ve ever wanted to create your own set of crazy wingdings, you can load up the PDF in an editing application like Adobe Illustrator and fill in the font-grid with anything you wish—hand writing or otherwise.
