The forming fabric includes a monolithic plastic sheet with water drainage holes therein. The sheet has an embossed outer surface with generally rounded projections and generally rounded depressions. Each of the projections has a height of at least 125 microns. The embossed outer surface is configured for contacting the fiber suspension. The embossed outer surface of the sheet is formed using a calender having at least one embossing roll.
