Paper positioning

When describing folding sequences and moves it is important to ensure that the paper is orientated in the same way as the instructions have been written.
Therefore we will be using the following conventions;

Imagine that you are sat at a table. The nearest edge of the table to you is perfectly straight, and runs horizontally from left to right.
This edge is the "Horizontal Reference"- HR
Directions will use this HR as a base line.

An imaginary line at 90 degrees to HR and parallel to the floor is the Vertical Reference - VR

Vertical In a direction perpendicular to HR
Horizontal In a direction that is parallel with HR
Closest Edge The edge that is closest to you and the table's edge if the paper is lying on the table
Furthest Edge The edge of the model that is furthest away from you if the paper is lying on the table
RAT Right Angle Triangle
Raw Edge This is the edge of the original square
Top Layer When there are 2 or more layers, this is the layer that is closest to the ceiling. (This layer may, itself, consist of 2 or more layers)
Left Hand The left end of HR
Right Hand The right end of HR
Crease Verb: To fold and unfold
Crease Noun: The mark left in the paper from a previous creasing
Fold To fold the paper into a specified position and/or along a specified line and to leave it there.
Blintz Verb/Noun: To fold all 4 corners of a square to the centre point. Named after a traditional Russian pastry
Turn The Paper Over Flip the paper from right to left, pivoting about the VR. Similar to turning a page in a book.
Rotate Without picking the paper up, revolve it about its centre point in the direction and angle specified
