Black, 45" wide, 100% polyester interfacing. It is stable and does not stretch on the lengthwise grain. It has substantial stretch on the crossgrain.
Imported and a favorite of many European designers.
Very light weight support with no bulk for lightweight silks, cottons and sheers and very light knits.
Test it for suitability for underlining sheer fabrics.
Consider cutting it on the crossgrain for fabrics that tend to stretch; test first.
Great for underlining garments.
