It may take some practice at first, but you'll soon be making these funny ghosts out of plain paper. Make sure you fold exactly on the lines, then your ghosts will be the most beautiful. There are also two slightly more difficult folds, both for the arms / wings. But practice a bit and you'll get the hang of it, after that the folding is easy peasy!
How to make Origami Ghosts
Place the paper square diagonally in front of you.
Fold the bottom point exactly onto the top point.
Unfold the paper and move it half a turn.
Repeat: fold the bottom exactly on the top again.
Fold open and fold 3 of the points inwards.
Turn the folding upside down.
Then turn the point downwards.
Fold the point as you see in the picture.
Turn the point of the folding downwards.
Fold both sides double up to the middle line.
Take the top of the arm and fold it downwards.
Do the same on the other side.
Fold the bottom point narrower.
Fold the points of the arms and tail forward.
Draw eyes and a mouth on your ghosts.
BOOOOOOOOOOOOOOOOOH, your ghosts are ready!
Happy Halloween!
