Origami Butterfly

I made this Origami Butterfly which I initially found via cut out and keep but the instructions were not detailed enough so I looked for a YouTube tutorial:

I am really happy with the outcome although it’s tricky when making several folds with thick paper. I used paper from an old children’s book. I am planning to send some in the post to my sister and I am planning to create a ceiling full of origami creations (hence the purple string).
