Vlieseline say:
H 609 is a lightweight, fusible knit interlining, made out of fine Polyamide yarn. This very special construction grants a very soft and elegant hand feel. Due to its extreme elasticity in warp and weft direction, it is an ideal interlining for large and small part fusing of very elastic high class outer fabrics, e.g. Jerseys. The excellent adhesive coating grants easy application by hand iron and outstanding adhesion even after many cycles of care treatment.

Poppy Bear Fabrics Says: This feels like the softest floatiest thing ever. When adhering do NOT put your iron on the shiny side because you will ruin it! Shiny side goes fabric side down. To be used in areas like crotch/snap plackets or to add strength to collars etc on stretch fabrics.
