Madeira Magic Pen Air Erasable - Purple
For use on all different types of fabric and more accurate, convenient and quicker to apply than marking with pins or stitches.
The pen has a fine tip and a thicker tip (one on either end), both making a purple line on your fabric, quite clear enough to see where to cut once you have measured or transferred a pattern shape.
The line disappears within a couple of hours, depending on nature of fabric.
Test on scrap before use
