These are thicker diameter flower head pins that are used to pin a quilt top down when doing a full float. There are 100 in a package. Because of the thicker diameter they won’t bend out of shape very quickly. These are not to be left in the quilt top when preparing a quilt to be turned on a longarm frame. The best pins to use on the sides if you plan to leave them in the quilt so you can turn the quilt are the “fine” flowerhead pins with the red and coral tops.
