I can’t find where I folded the model from, but I really like it. It’s very simple, but the form is right, it stays closed because the front heart locks into the far one on the top. You can open it and write your message inside, or use smaller paper and spread them around your loved ones.
Paperkawaii published the video tutorial for this box a while ago. She has other cute models, but isn’t afraid of cutting and gluing – not my thing. This model is pure origami though. Beware, the music she puts on the videos is really irritating, but you can just shut it off, since she doesn’t talk.
It is folded from 2 sheets of 20cm paper (from a nuinui kit).
It is really sturdy, closes and opens well. I’ll probably fold it again :)
