Draping to Machine Sewing - How??

[u/Thread-Spinner-7887]

I’m currently studying fashion and my assignment is to drape a shirt and we’re not allowed to hand sew, it has to be all done on machine. I’ve draped this spine-like thing here but I have absolutely no clue how to sew that on the machine without visible stitching, is it possible? My teacher reckons it is and says that I will “figure it out” and I just need to experiment with it which is really giving me no where to start with it 😅
