I have not finished reading all the messages... but when I went to college, the dorm had a sewing machine available to the residents for just that kind of thing. Which is what I used the first year of college.
Then I bought the simplest, and most basic machine used I could afford (an old Singer black machine for $25).
Perhaps BJU has in their living quarters or in some activity area a sewing area for the use of their students. Also, with luck she may find someone who has a machine there for her to borrow.
Since I had a machine during my second year in the dorm, it did get borrowed a couple of times.
Later during my junior year of college after working at an internship where I got paid a decent wage (enough in 6 months to pay for the last two years of college) I bought a more serious but lightweight machine. It was a Viking Vanessa (Husqvaran 3610, 5610, whatever)... something I have seen a few times on the used machine shelf at a couple of sewing machine stores. That worked quite well for over a dozen years until I discovered Cordura.
