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.
Fold the top corner back in. Work the folds so that their lines are well-defined.
Bend the top corner back to get a trapezoid shape of your paper.
Unfold the piece of paper completely. In the center, the fold lines form a square and divide it diagonally.
Lift the lines forming the square and gently iron the folds.
Click on the sides of the square, connect them – and the center of the sheet itself will “collapse” inside.
Take the two right corners of the square and connect them.
In the photos you can see what result we achieved and how the sharp tip of the base shape disappeared inside.
