This invention relates to a unique method of fabricating a dry-formed, adhesively bonded nonwoven sheet and to the sheet formed thereby. The method of this invention includes the steps of forming a low integrity, dry-formed fibrous web having a basis weight in the range of from about 30 grams per square meter to about 170 grams per square meter; embossing the web to provide spaced-apart densified regions and high loft regions with the densified regions covering from about 15% to about 40% of the planar area of the web and having a density greater than about 0.150 grams per cubic centimeter, and with the high loft regions having a density of less than about 0.100 grams per cubic centimeter; stabilizing the embossed pattern with a binder for retaining a differential density within the embossed web as it is directed to a creping surface and creping the embossed web by adhering it to a creping surface under conditions which do not destroy the differential density in the embossed web and employing a creping doctor blade which foreshortens the web as it removes it from the creping surface for forming a creped, aesthetically pleasing nonwoven sheet of this invention in which the surface appearance resulting from the creping operation is controlled by the embossed pattern.
