Vilene Stretchfix T30 tape comes in a package of 30mm x 5m. 100% PU. Transparent.
Used for soft hem construction in elastic garments.

Iron on Stretchfix T30 along the edge with a dry iron and a setting of 2-3 dots for 10 to 12 seconds. Then fold over the hem at tape width, and iron (before removing the paper). This allows you to immediately define the hem width and fold without the need of measuring.

Allow the paper to cool down completely and peel it off. Fold the hem upwards, cover it with a damp cloth and press on the iron (setting: 2-3 dots) for about 10 to 12 seconds step by step. Do not push.
