This invisible magic tape is ideal for pattern making.
You can easily draw and erase lines across the tape. The small width makes it very easy to work with.
If your pattern paper is not too thin, you can easily remove the tape and to some extent even reuse it.
Perfect for when you make fitting alterations to sewing patterns and need to cut into the model to make the necessary changes.
Also perfect, if you make your own sewing patterns and need to move darts or add width into a model.
