This BTS mini book with ribbon tie closure is super easy to make. It’s folded from a single sheet of square paper. It only takes 5 minutes to fold, and no glue is required. This model is an arrangement of traditional origami, a Masu box.
I have included the FREE printable BTS illustration. All you need to do is print it out, trim it on the line indicated and follow the instructions from my video tutorial on my YouTube channel to make it into a mini-book. You can print a solid colour on the opposite side of the A4 if you like, or decorate the cover with colour pencils.
You can fold it from a blank square paper and make it your mini notebook for just about anything.
