1.- Define a square frame. (A-B-C-D same length sides).
2.- Screw the frame "A" to the aluminium strip "x"; join only one side of the strip with a "skip-one in x" pattern, leaving one loose but in place.
3.- Weave the grid in a "2 up - 2 down" pattern, in both "x" - "y" direction.
4.- Screw the frame "B" to the aluminium strip "y"; join only one side of the strip with a "skip-one in y" pattern, leaving one loose but in place.
5.- Apply force in corner "A-D" and "B-C" with a tensor in order to get them closer.
6.- Apply force in corner "A-B" and "C-D" with a tensor in order to get them closer.
7.- Play with different tensions and control points in order to get different surfaces. Assure to always have symmetry with the control points.
