A paper sheet, in particular for use as toilet tissue, consisting of at least one ply of absorbent crepe paper with a basis weight of 12-35 g/m<2>, and having first (10) and second (2) projections forming first and second patterns respectively. The first pattern consists of pattern elements that each consist of at least one of said first projections (10) and are relatively far apart, while the second or background pattern includes said second projections (2) arranged closer together between said pattern elements. The pattern elements form a graphic pattern by being distributed in a concentration of no more than 0.5 elements per square centimetre, the first projections (10) forming said elements have a linear top surface with a width of 0.1-2 mm, and the second projections (2) are distributed in a concentration of at least 30 and preferably 40 per square centimetre, and provide most of the functional features of the paper.
