I have no idea how to make it into a downloadable file thingy. these are really intended to be headers, the first letter of the page. so all you have to do is cut and paste. that's why the image size is so big.
Do you have any intention to make an actualy font out of them? Or do you mind if I'll do? I know you said it's free for use, but I rather wanted to ask again. I'd love to make a font out of this and the two other alphabets you posted.
