Pen-style Chaco liner's fine point permits accurate drawing of both straight lines and freehand curves. The fine point makes lines and marks more visible and is easy to use with a straight edge ruler.
We refill with the iron-off Miracle Chalk! And you only need one chalk liner to mark all fabric if you add just a tiny touch of cinnamon powder to your powder, it will then show up on your light-colored fabrics! (of course, you do have to brush that away with a stiff brush or go ahead and wash your project to remove the cinnamon!)
