This disappearing pen will be appreciated by anyone who sews, embroiders, quilts or does other techniques where you need to draw a pattern on fabric that can simply be removed after stitching, leaving just your beautiful embroidery. Working with this pen is simple and, thanks to the extra-fine tip, precise too, so you can mark even very detailed patterns onto fabric. The line the pen leaves is thin and purple, and shows up well on almost all fabrics (perhaps with the exception of really dark ones). The line itself disappears after a few days (depending on the specific fabric used); alternatively, if you want to speed up its disappearance, you can use plain water or a damp cloth and gently rub the line away. Before you start creating, we recommend testing the pen first on a small scrap of the fabric you'll be working with. To make the pen last as long as possible, always store it with the tip pointing down.
