Woven Fusible Interfacing Medium 112cm FT620
Interfacing is a textile used on the unseen or "wrong" side of fabrics to make an area of a garment more rigid, stiffen or add body to fabric, such as the interfacing used in shirt collars, strengthen a certain area of the fabric, for instance hat brims.
Woven Interfacing – your fabric should still look, feel and move like fabric, albeit a thicker one. Typical woven interfacing may take your quilting-weight cotton up to more the feel of a decor weight fabric. But it still feels like fabric.
This is a Medium Weight interfacing.
