I've found some great halloween origami videos from all around the world from people who are celebrating halloween, and they are getting into it by making really great decorations! See below for an easy origami bat, a fun jack-o-lantern and a more challenging (but absolutly adorable) origami cat!
Here we go!
Origami Bat
This halloween bat is one of the easiest and best origami bats I've seen - many bats can be very over-complicated and confusing, but this one is simple and looks so great!
Origami Jack-O-Lantern
I love these videos by "PantyMython" on youtube. They are a really fun way of doing instructional videos - and this jack-o-lantern looks fantastic! The origami jack-o-lantern is basically a Waterbomb model, with a stem (and a scary face, of course!)
Origami Cat
There are a couple of videos on youtube showing this type of cat - I think this one is the most straight-forward. It's not an easy model, beware! But if you have done a little bit of origami before, you wont have any trouble, and it will be well worth it - look how cute he is! Of course, making him with some black paper will look awesome for halloween decorations!
