Organ Quilting Needles are suitable for quilting and piecing. They are also recommended for sewing buttonholes. The slender, cone-shaped tip of the needle pierces smaller holes, and the swelling of the lower material is markedly reduced. Likewise, the puncture resistance is reduced by the slim tip shape. The Eco Pack reduces plastic waste. Organ Sewing Machine Needles, Quilting, 3 of size 75 and 2 of size 90, by Organ Needle Co., LTD.
