This really is magic dressmakers chalk - now you see it, now you don't!
This white chalk makes fine markings on your dark fabrics, and disappears with heat from an iron or self erases after 2-3 days. Brilliant therefore for marking fashion fabric on the outside or inside and leaves absolutely no trace!
Works on most materials including wool, crimplene, jersey, silk and coutil.
You simply mark your fabric, and when you need to get rid of the mark, you can iron it away! Beware though, if you dont iron it away, the mark will disappear on it's own after 7 days.
Always test an inconspicous area first.
Can be sharpened with a craft knife or the blade of sharp scissors.
