Claim:
1. A method for making a bulky sheet comprising directing high pressure water jets to a fiber web to entangle the fibers of the fiber web with themselves to form an entangled fiber web, placing the entangled fiber web on a first patterning member having apertures in a predetermined pattern, and subjecting the entangled fiber web placed on the first patterning member to high pressure water jets to cause part of the entangled fiber web to project into the apertures of the first patterning member, the first patterning member comprising a plurality of first wiry members extending in one direction and arranged at a predetermined spacing and a support having a plurality of openings, and the support underlying the plurality of first wiry members, wherein the support of the first patterning member comprises a plurality of second wiry members extending in a direction different from the direction in which the first wiry members extend and arranged at a predetermined interval, at least one of the first wiry member and the second wiry member has a nearly triangular cross-section and is disposed with its triangular cross-section pointing up or down, and the first wiry member has a nearly triangular cross-section and is disposed with its triangular cross-section pointing down, and the second wiry member has a nearly triangular cross-section and is disposed with its triangular cross-section pointing up.
