Erasable Fabric Pens - Set of Two

These pens, one blue, the other red, are non-toxic and a great alternative to tailor's chalk. Trace or draw onto your fabric, then iron-off with a cool, dry iron, or rub-off with the attached eraser. 

Suitable for light coloured fabrics, and you can erase and re-mark without damage to fabric, though I would suggest you test on a piece of fabric first especially if it isn't cotton.
