The Prym assortment offers a special edge tape, reinforced by vertical threads, for stabilising armholes, front edges, lapels, and much more. This 20 mm, narrow tape is ironed along the round cutting edges and effortlessly provides support and stability. This allows for heavily-stressed edges, such as necklines or pocket openings, to be sufficiently reinforced, even with a diagonal grain line. This white or graphite-coloured interfacing is made of 100% polyamide, is ironable, and can be washed at 40 degrees. The card contains a roll with 10 m of edge tape interfacing.
