Well, I just discovered several things.
First: the 201 will sew through two layers of that vinyl without any trouble.
Second: the polyester upholstery thread we used years ago is so heavy that the machine will sew with it,but getting the bobbin tension right might not be do-able. Or will take some doing, don't know yet as I hate to mess with the bobbin tension.
Third: A size 16 jeans needle works just fine.
Now to fine tune our efforts and do this thing.
