Last week I discovered a very useful site – Fontstruct. It has easy-to-use tools for constructing fonts; you can share your fonts in the online font gallery, though you don’t have to; and you can also download and edit fonts created by other users of the site. Once you’ve signed up to the site, which is free, you can start making fonts. The finished fonts can be saved on the site and downloaded.
I’ve started constructing a font for an alphabet losely based on British Sign Language finger spelling that I’ve been playing with for a while. I’ll post it on Omniglot once I’m satisfied with it. This may take quite a while though.
[Update] My finger spelling-based alphabet, which I named ‘Fingers’, is now online.
