Description of the figure: This is a very simple butterfly. Its 4 wings are represented by 4 triangles, of which two point to the left and right and two, slightly rounded, backwards.
A fold exactly in the middle of the figure represents the body. In this figure, only one side of the paper is visible, in case of using two-sided paper.
For this figure you need a square piece of paper. If you already have it or know how to cut it, I recommend you skip to step 5:
1: Place a rectangular piece of paper (a4 can be used to start) with the shortest sides to the left and right, the longest sides to the top and bottom.
2: Bring the left edge to the top edge. Mark the fold and leave folded. A triangle should form from two layers of paper. a part of the first layer protrudes from the triangle. It has the shape of a rectangle and is on the right, where we did not make any folds.
3: Cut the rectangle that protrudes from the triangle. Try to make the cut as neat as possible.
Alternatively, weaken the paper and tear it along the fold line you have made.
4: Unfold the remaining triangle. If we have followed the steps correctly, we should have a square.
Now, we'll make a triangular base, water bomb base, or basic triangular shape. If you already know how to do this, go directly to step 14.
5: If you have a piece of paper with different colors on both sides, place it with the color you want to see facing up. In any case, we must have it in the shape of a square, with the edges pointing to the left, right, top and bottom.
6: Bring the bottom edge to the top edge so that we have a rectangle. Score the crease and unfold so that our square now has a horizontal center line.
7: Bring the right edge towards the left edge, to obtain a vertical rectangle this time. Mark the fold well and unfold, so that our square is now marked by a cross.
8: Flip the paper from right to left, as if we were turning the page of a book. The previously valley folds will now be mountain folds, which means they will look slightly raised instead of slightly dipping below the square.
9: Place the square in the shape of a diamond. This means that the edges will now be diagonal and the corners will be pointing top, bottom, left, and right.
10: Bring the right corner to the left corner, so that we obtain a triangle. Mark the fold well and unfold. We now have a center line running from the bottom corner to the top corner.
11: Bring the upper corner to the lower corner, obtaining a triangle but this time with its longest line horizontal. Mark the fold and leave folded.
12: Attention, because this step is easier to do than to explain: raise the triangle that we obtained in the previous step, with the last fold pointing towards the floor and the tip towards the ceiling.Hold the left and right corners, one in each hand, and push them in, the right to the left, and the left to the right. The paper will collapse through the folds we made, so that we will obtain a three-dimensional figure made up of 4 triangles that point forward, backward, left and right. It can also be seen as a 4-pointed star. slide your fingers down the center of the figure, to smooth the folds.
13: Bring the front flap towards the right flap and the back flap towards the left flap. We get a triangle formed by two flaps on the left and two on the right. these flaps are separated by a line that can only be seen by lifting the top flaps. The figure as a whole has a closed end and an open part, which is a straight line. We will place it back on our work surface, with the closed end pointing away from us, the open part pointing towards us and the other two corners pointing to the left and right. We now have a waterbomb base or the basic triangular shape!
14: bring the right corner, only the upper flap, towards the closed tip. A diagonal fold is created that forms a smaller triangle on top of the large right triangle.
15: Repeat step 14 with the upper left flap. Now, on the big triangle we have a rhombus divided in two by a central slot. These two small triangles that form the rhombus will be the upper wings of the butterfly.
16: Flip the paper from right to left as if we were turning the page of a book. Now, on the visible or touchable side of the paper, we have a large smooth triangle.
17: Raise only the closed tip, without touching the two folded triangles in steps 14 and 15. We will bring it towards us, so that it exceeds the open part of the figure. This fold will make the wings round up and a small triangle will protrude, approximately one centimeter long if we work with a square from an a4 sheet. This already has a bit more of a butterfly shape, doesn't it?
18: Flip the paper from right to left again. Now you can see the wings of the butterfly, separated by a slit, and the little triangle that sticks out.
19: Fold along the line that separates the small triangle that faces us from the rest of the figure. We have to achieve that this surrounds all the layers, so that it serves as a hook that keeps the butterfly in its place, and no longer protrudes from the figure but remains on top of it.
20: To finish, fold the figure in half from left to right, following the central groove and so that the last triangle that we folded is inside the fold. This fold will form the body of the butterfly.
Our butterfly is finished!
