After a morning filled with being awake, an lunchtime filled with existential angst, an afternoon spent napping and an evening at work, I came home and got to pinning monsters for the night. It's good that it's a very much "in front of the TV" kinda task, because it's quite frustrating.
Because you sew and turn out and stuff the arms first, and because monsters are under no obligations to conform to the ratios we find pleasing in a person, often their arms are longer than the boddies they have to be pinned inside of.
My tip, for anyone who wants to make monsters of their own, would be to sew them once, over the edges that have arms or horns in them, and then shove the arms well out of the way and sew the groin area. If you try to do it all in one hit, the position of the arms can get distorted, and they'll be pointing in all sorts of weird directions.
Also, the movie RED is very enjoyable, and good for watching while pinning monster bodies.
