1. A method of making and packaging a compressed hollow coreless roll of absorbent paper sheet comprising:
providing a roll of absorbent paper sheet by winding the sheet about a forming core member having a diameter in the range of 30 mm to 75 mm;
removing the forming core member such that there is provided a hollow coreless roll of absorbent paper sheet with an axial cavity having a diameter in the range of 30 mm to 75 mm;
compressing the hollow coreless roll with opposing forces bearing against opposing lateral surfaces of the hollow coreless roll, such that the axial cavity is substantially collapsed into an elliptical void having opposing long side walls that are planar and parallel to each other and in surface contact with one another over at least 60% of their area; and
packaging the compressed hollow coreless roll so that the axial cavity of the compressed hollow coreless roll is maintained in the substantially collapsed configuration.

14. A method of delivering absorbent paper sheets comprising:
providing a roll of absorbent paper sheet by winding the sheet about a forming core member having a diameter in the range of 30 mm to 75 mm;
removing the forming core member such that there is provided a hollow coreless roll of absorbent paper sheet with an axial cavity having a diameter in the range of 30 mm to 75 mm;
compressing the hollow coreless roll such that the axial cavity is substantially collapsed, wherein the compressing occurs via opposing forces bearing against opposing lateral surfaces of the hollow coreless roll to produce an elliptical void having opposing long side walls that are planar and parallel to each other;
packaging the compressed hollow coreless roll so that the axial cavity of the compressed hollow coreless roll is maintained in a substantially collapsed configuration that has the opposing long side walls of the elliptical void in surface contact over at least 60% of their area;
re-forming the compressed roll by expanding the substantially collapsed axial cavity;
mounting the re-formed compressed roll about a spindle; and
dispensing absorbent sheet from the outer periphery of the re-formed roll.
