Tutorial on folding a heart-shaped box from cardboard, print the drawing [see here], then cut and origami, and you can easily complete the production of a beautiful gift box!
Material preparation: patterned cardboard, scissors, brad nails, ribbon or ribbon, glue or double-sided tape, paper flowers.
First print the template on the back of the cardboard, cut it along the solid line with scissors, and then fold it along the dotted line (valley fold line).
Turn over the front, that is, the printing side is facing down, and take another piece of paper and cut out a heart shape. The size of the heart shape is the same as the heart shape in the picture above (shown in the black area a). Then cut out a semicircle and glue it to the front of the bag (handle). You can refer to the finished product. Take another piece of paper, as shown in the black area b in the picture, cut out a long strip, and stick it with glue. Attach a long ribbon to the top of the black area b (the position shown by the dot in the picture) to cover it. The edge of the paper that was just glued on. Apply glue all over the gray areas c, d, e and f. Turn over to the back, that is, the printed side is facing up, fold the two sides upward, coincide with the handle, that is, the heart-shaped position at the upper end, and fold the semicircle through the hole downward. Stuff the four glued areas into the bag and press them to both sides so that they stick firmly to both sides.
Next make the decorative flowers for the bag:
a) The brad nail goes through the center of the paper flower;
b) Cut a ribbon of appropriate length and fold it in half;
c) Cut a piece of paper wider than the ribbon, and cut it at a 45-degree angle;
d) Drill a hole at the midpoint of the bottom of the semicircle that is folded downward in Figure 3. The size of the hole is determined by the brad nail;
e) Thread both the ribbon and the paper tape on the brad nails and pass them through the holes punched in d.
