Organ Quilting Needles are suitable for quilting and piecing. This pack contains three size 75/11 quilting needles, and 2 size 90/14 quilting quilting needles. They are also recommended for sewing buttonholes. The flattening angle of this needle is larger, which reduces the distance of the flute from the rotating gripper. Thus, the gripper can securely catch the thread loop even if the looping becomes unstable. The specially shaped groove contributes to the formation of larger thread loops and supports the upward movement of the upper thread. This avoids missing stitches. 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. Favorite Uses: Great for Quilting and piecing with (lighter) 60 wt. Polylite, 50 wt. Cotton and (heavier) 30 wt. Cotton.
