Started over from scratch this afternoon after learning a few more things about FontForge, got a reasonable set of glyphs in place including numerals and all of the punctuation characters I actually know how to type.
This is about as thin as I think is still readable; I think I'll work out regular and bold versions as well to give it a proper set of options, and then start thinking about modifications for the stencil version.
Still have a bunch of niceties to think about, kerning and shit, but it's neat to be able to say Poof! It's A Font.
May or may not stick with that name, but the fact that the whole thing is intentionally built out of just a straight and a curvy bit of piping feels on point.
This is Actual Font Output, which is exciting; FontForge is pretty intimidating but I'm getting the hang of the basics at least, and was able to put together the lowercase set of letters this morning without too much hair-tearing.
No uppercase, numerals, punctuation, etc yet -- I've got sketches for most of that but have to draw 'em out in FontForge still. Not totally clear to me whether I'll be better off in the long run drawing in FontForge or drawing in Inkscape and importing, because boy FF feels fiddly in a lot of ways and bogs down a lot, but being in the native environment probably has benefits in terms of avoiding compatability headaches and such.
