Been working on a light weight of FSP. I've worked hard to keep all of the letters the same physical width as the regular weight of FSP, meaning that mixing weights won't result in thinner-looking letters.
Anyway, this is what is done so far. I've yet to finish the numbers and punctuation, and then there are all those non-English characters.
Oh, and the tracking hasn't been adjusted yet, so the letters in this preview are going to appear like they've been tracked out a lot. Ignore that, as it's just a leftover from the regular weight.
