  • Patent number: 10378144
    Abstract: A handicraft roller, used for pressing a piece of cloth to put a sharp crease or fold in the fabric, includes an elongated grip with first and second ends spaced from each other in the longitudinal direction of the grip. A rolling member is attached to the first end of the grip so as to be rotatable about a predetermined axis. The rolling member is made up of a constant diameter portion and two decreasing diameter portions flanking the constant diameter portion. The constant diameter portion has an outer diameter that remains constant over a predetermined length of the axis. Each of the decreasing diameter portions has an outer diameter that decreases with increasing distance from the constant diameter portion along the axis.
