My girl, Rosie, just turned me on to a new site, FontCapture, that allows you to make a font from your own handwriting. I've seen this done before, but it's never been made this fun and easy. Plus, it's free and compatible with both Macs and PCs, so there are just 4 tiny steps between you and your very own font.
First, just print the font template. Then, fill it in with your own handwriting with a thin black marker. Be sure to keep your eye on the indicated baseline. You're already almost done. Now, scan the template back in and upload a jpeg or png file through 'Step 3' of the site. Give your personal creation a name, download the generated files to your computer —and voila; you're a type designer.
