Mechanical chalk pencil + 6 ultra-fine white leads - ø 0.9 mm. The chalk is a historic accessory of sewing and the clothing industry. The chalk pencil is indispensable for marking pattern lines: darts, placement of trouser and baggy (African) trouser pockets, frill placement...it enables to demarcate the cutting and folding areas. Its easy handling will enable you to make very precise, and more intent tracings than with a traditional tailor's chalk.
 
Usefull in patchwork for making half square triangles, and quilting lined for quilting along
 
Always do a test on a piece of fabric to verify that the chalk rubs out normally. A button with a removable lead is located at the upper end of the mechanical pencil whose holding mechanism changes the lead when it is pressed.
