Iron on interlining with stabilising longitudinal threads that prevent the top fabric from hanging out, here you should take into account the thread direction. It feels pleasantly soft and is 90 cm wide.
Place the interfacing with the covered side down on the wrong side of the outer fabric and first fixate step by step at low temperature to prevent distortion. Then cover with a damp cloth and press the iron on step by step for approx. 8 sec. Do not make any ironing movements.
