It is especially well suited for pinning lace, eyelets or loose woven embellishments to fabric because the head will not slip through enlarged openings. You can also lay rulers flat on them when marking or cutting. The heads are not iron proof so keep them away from the heat. These pins come in three different diameters to provide strength without stressing your fabric.
