1. A method of making a fabric-creped absorbent cellulosic sheet, the method comprising:
compactively dewatering a papermaking furnish to form a web having a consistency of about 30 percent to about 60 percent;
creping the web under pressure in a creping nip between a transfer surface and a structuring fabric, the structuring fabric including knuckles formed on warp yarns of the structuring fabric, with the knuckles having a length in the machine direction (MD) of the absorbent sheet and a width in the cross machine direction (CD) of the absorbent sheet, wherein a planar volumetric index of the structuring fabric is defined as a contact area ratio multiplied by an effective pocket volume times one hundred, a planar volumetric density index of the structuring fabric is defined by the planar volumetric index multiplied by the pocket density, and the planar volumetric density index of the structuring fabric multiplied by a ratio of the length of the knuckles to the width of the knuckles is at least about 43; and
drying the web to form the absorbent cellulosic sheet.
