I’ve long wanted a font based on my own hand. The easiest, cheapest and quickest way is MyScriptFont. To get my personal script, I wrote out an alphabet on their printed-out template (block letters only, no cursive), scanned the sheet and uploaded it, and then installed the scaleable font they handed back. It’s free. Takes only minutes.
Once I had my handprinting font, I figured I could quickly make other homemade fonts. It’s a quick cheap way to make any kind of unique hand-drawn font you want.
