Reply To: Interfacing

Oh boy, sounds like your interfacing is too heavy.  Is it woven, non-woven, or knit?  Most fusable interfacing is the non-woven type and not very flexible but if it’s knit, it might very well soften.  Not knowing what you have, make a small sample (even something as small as a 5×5 square) of the fabric, interfacing, and lining, wash it and see what happens.  To me, that’s your best bet.  Then you can decide if you want to take it apart or not.  Sorry I’m not being of much help.
