How to fold back a foldable travel bag

Prepare four or five square pieces of paper and fold the inner core first. Fold both sides of the square paper in half and then open it. Align the two sides of the paper with the center line and fold them inward. Fold the two sides in half again, and then fold the two ends with the fold line inward.

2. Open one of the folded corners, press the bottom edge to make a diagonal line and fold it outwards, fold the top edge inward to make a diagonal line and then fold it inward, and compact it as a whole. , the other three corners are processed similarly, and an inner core is ready.

3. Make the other two inner cores, glue the adjacent sides together with solid glue, and set them aside for later use. Fold both sides of the square paper used to make the outer cover in half and then open it. Align the two sides of the paper with the center line and fold them inward respectively. Leave a certain gap where the two paper edges are aligned with the center line. The two sides should not be directly facing each other to facilitate the next step.

4. Put the outermost side of the glued inner core into the paper seam in the middle of the outer skin, and then wrap the outer skin around the inner core. Finally, you will find that the outer skin is longer

< p>5. Fold the end of the paper upward for a certain distance, then align it with the bottom edge and fold it back. Cut off the excess paper from the last crease
