Phew, what a day.
I finished painting Marion (she’s fully sighted now, thank you very much) and actually managed to make one latex puppet today. YES. I KNOW. I was thrilled, too. It’s far from finished—there’s all the patching and trimming and fur-gluing and skin-painting to do—but at least I’ve proven that my molds can actually create puppets. So there’s that.
To illustrate how time-consuming this process is (3.5 hours, just to do the part shown below), I’ve made a little photoseries:

After the figure is sculpted, the mold made and dusted with mold release, and the latex mixed (according to the particular warmth and humidity of your studio), you can finally pour the mix.

When both sides are full and the armature is in place, take a deep breath and squish the two sides together before it hardens/spills out the side.

Let it bake for 2.5 hours, then pry it apart with a crowbar or a screwdriver. Or, if you’re hardcore like me, your bare hands. Before waiting for it to cool. (Ouch.)

Gently peel the latex off the mold. Swatting your friend’s hands away when she tries to help is optional.

Trim off the excess latex with a pair of mustache scissors. Yes, that’s really what those are. Yes, the latex fumes made that a lot funnier than it should have been.
And then you’re done! Haha, just kidding. You’re never done. But you do have something resembling the photo up at the top. Voila!
