I am having trouble finding an interfacing I like for Polyester shantung. The smooth side is slick and doesn’t always bond well. The hand feels a bit like taffeta afterward. I tried fusible tricot thinking that would be the softest choice and it likes to pull away from the smooth side of the fabric when using the nubbed side for the fashion side of the garment. Other things have been poor choices also and haven’t bonded well. Interfacing on the nubbed side to use the opposite out is also a problem with bonding.
