First find a piece of colored A4 paper, cut it slightly wider than the photo, then fold it up and down, and fold it as many times as there are photos.
If you want to simply take pictures, you can put the photos on both sides like Dali. Finally, stick the small mechanism in the appropriate position of the notebook with double-sided tape. With a little decoration, it's done! Is it easy to learn and save? I believe that everyone can use small organs flexibly and will soon be able to sit on the explosion book!
Recording what has happened can be used to record the particularly meaningful things in your life, such as reading good books, eating delicious food or going shopping, taking photos, traveling, meeting old friends and so on. Or just some special little things or even a running account of what you did this day, as long as you like and are happy, anything can be done.
