    Abstract: The present invention relates to a smoking tip, a filter sheet for forming a smoking tip, and a booklet for forming smoking tips. In one aspect of the present invention, a filter sheet comprises: a sheet having a fabric layer thereon: wherein the sheet is rollable to form a smoking tip, and the fabric layer, when the sheet is rolled, forms a filter for the smoking tip. In another aspect of the present invention, a booklet comprises: a plurality of sheets, each sheet having a fabric layer thereon; wherein each sheet is rollable to form a smoking tip, and the fabric layer, when the sheet is rolled, forms a filter for the smoking tip. In another aspect of the present invention, a smoking tip comprises: a roll with a non-woven fabric material therein, wherein the non-woven fabric material forms a filter for the smoking tip.
