Origami Sink (Method 2)
Folding under the conventional name “shell” – is one of the techniques used in the process of making figures in the technique of origami.
To fold the paper into a “shell” means to wrap the protruding middle of the sheet inwards. The difficulty is not to wrinkle the core that we are wrapping. Let’s try this technique on example – “Standing core”.
Let’s start with a basic water bomb shape. Our goal is to wrap the top corner of the triangle inside, which in the unfolded sheet is the center.
Fold the triangle in half so that the fold line goes through the center of the top corner to the base, then unfold it back.
Unfold the piece of paper completely. In the center, the fold lines form a square and divide it diagonally.
Click on the sides of the square, connect them – and the center of the sheet itself will “collapse” inside.
