Yarn support comprising an inexpensive compressible core, especially of laminated paperboard, with a water-resistant covering, especially of parchment, with the improved feature that the unwinding end is covered by parchment with a smooth transition from the winding surface to this covered end, so as to avoid snagging of the yarn during unwinding. Such yarn support may be prepared economically by making partial internal and external cuts through the core material and removing the end portion to give an external flap of axial length equal to the wall thickness of the support, and burnishing to fold and smooth this flap over the exposed ends of the inner layers of core material, to compress the core material in the flap against the ends of the inner layers to give a rounded configuration and to fair the flap into the internal surface of the support.
