Caley, with Covid there is indeed a run on sewing machines. Freezers too... sounds like I might get one of those by Labor Day.
You need a zig zag suitable foot, and a single needle position foot, and I really like those quilter feet that give you your 1/4" on both left and right, and markings for front and back. There are sewing techniques where this is really nice, but like most stuff it is always optional. The nice thing about Brother feet is most are designed to be interchangeable and are often available at your local store as well as easily on line.
