Help someone??

I am trying to sew a skirt that is just regular kinda spandex fabric, with a metallicy type fabric underneath, that is like plasticly on front, like it is for a Halloween costume, but my machine won't sew that, the bobbin won't work.

Does anyone have any suggestions on how I can make it work???
I don't really want to have to hand sew it.
