Final flip book print

I pint 3 flip books for test yestday. The outcome is good and not too expensive. But I prepare to bind the problem was come. The worker said the book is too small to bind. So I take it go home to bind them by myself.
I research some way to bind the book in very old chinese way. Which is no pollution, strong, easy, and nice.

I didn't do the absolutely same bind. I change a little. It would make my book stonger.

I make a transparence plastic paper cover. It can protect I books.

Im very happy for the final book. Its looks fine.
