This is exactly what it sounds like, fabric made of tyvek. Unlike the hard structure tyvek sheets, this product is called "soft structure" and is soft enough to drape and feels very fabric-like. You'll probably want to melt and/or stitch it as it comes with a dimple like check texture. The checks are very tiny, but there's no missing them. Since it's soft like fabric, you can use it in many applications that the hard structure tyvek isn't suitable for. Please remember to be careful when heating and melting tyvek. Also, please ensure you have adequate ventilation to protect yourself from any fumes.
