J. CREATION OF THE MATRIX FOR THE "PILLOW"

a. A 15 cm by 15 cm cardboard is prepared, which folds twice and is then reopened.

b. Operating on the top left corner of the cardboard-matrix, we have to identify two points, in correspondence of which we will then drill holes.

c. These two points must be 1 cm away from the upper edge and 1.5 cm and 5.5 cm away from the left lateral edge respectively.

d. This identification, of course, could be done by operating on the matrix cardboard with a common row, instead we will do it by operating with the particular line that we have prepared: the multifunctional Ruler.

e. Operating on the top left corner of the cardboard-matrix, we superimpose the multifunctional Ruler horizontally starting from its GAMMA end, matching with the left edge of the cardboard, not the end of the Ruler but the segment we have drawn at 3 cm away from that end.

f. Through the first and third of the four holes on the multifunctional Ruler, we draw two rods on the cardboard-matrix.

g. The cardboard-matrix is folded twice, so as to obtain four quadrants and in such a way that the quadrant on which we have identified the two points for drilling are visible.

h. The drilling is carried out, involving in the drilling all the four layers that were formed in the cardboard-matrix as a result of the folding, and thus we obtain the eight holes that will be involved in the packaging of the mask.

i. Once the cardboard-matrix is open, the holes of one of the two sections are marked, from left to right, with the letters B2, A2, A1 and B1, while the holes of the other section, lower than the first, are marked, always by left right, with the letters B3, A3, A4 and B4.

j. The holes thus marked correspond to the holes marked with the same letters on the Matrix of the Forms Structure and Screen.

k. The Matrix of the Pillow Form is ready.
