Vlieseline Iron-On White Edge Tape 5m x 20mmLight weight fusible tape made of synthetic fibres, with stabilising vertical threads. For the stabilising of straight edges of e. g. shoulders, facings etc. on blazers, jackets and coats. Suitable for all fabrics. Iron on for around 40 seconds, applying light pressure. For round edges (arm holes, lapels etc), tuck the tape into small pleats and iron it on like this, rather than cutting into the tapes as this will destabilise the material. Washable at
