Air Erasable Embroidery Pen

It's okay but fades extremely quickly .

I thought I would test this pen out on some scrap material, to make sure that it would actually disappear over time. However, what I discovered was that it faded to nothing almost straight away, so it would actually be useless for what I wanted, which was drawing designs for machine free-motion stitching, as the lines would be gone before I could stitch them.

Brilliant service I can see so many uses for this pen
