Fold crossing theory

A single fold is a theoretical concept. On your body, any fold will inevitably meet another fold.

Fold's crossing point becomes fixed

When the center is locked in place, it restrains the movement of the skin around it.

Once a fold crossing is locked in place, it receives the pull  from your actions and positions.

FOLD CROSSINGS IN THE PALM OF THE HAND

Fold crossings in the palm of the hand

Some fold crossings are visible on the palm of your hands and feet and on your face. Press your nail into some crossings to ascertain how deep they are.

Dimples are fold crossings

There are dozens of fold crossings on this chin. If this one is visible, it's because it's larger than the others.

Fold crossing chimneys pin down the skin

Fold crossings bind the skin and create a crater. This button on a cushion does a similar job.

-Where are all the tensions relayed?
-In the center.

Stable fold crossing

Equal tensions on one fold crossing

Equal tensions on a fold crossing.

Destabilized fold crossings

Unequal tensions on one fold crossing

The tension is relayed to the following crossings along the fold.

The grid links the fold crossings

Any movement you make pulls on the neighboring crossings.
