Hi
@annieeg The fabric suggestions are:-
viscose, silk, tencel, soft fine cottons such as lawn
So yes I would think so. You might want to interface both sides of the collar for stability and try not to overhandle to avoid too much fraying.
I found the collar really fiddly to do and did hand tacking before the stitching (as pins were too long), slipstitch on the inside and then topstitch on the outside so it'll hold up through the wash and me wearing it (I'm quite hard on clothes).
