    I have unfortunat​ely moved several times in the last 5 years and cannot find the manual for my brother GX37 sewing machine. I actually have never unboxed it. Recently I needed to make something and when I sew the seams they are not catching from the bottom, I think. I finish a seam, pull it out of the machine, and the thread just comes right out. This is my first brother product, and I have to say I am not impressed. Why is this happening?
