It works beautifully for FMQ!
Be careful when approaching a point where there is a "stack" of fabric - where many seam allowances come together. The slant needle makes this machine a little more prone to needle deflection (broken needles, bent needles) than a needle that's oriented straight up and down. But, it's not difficult to work around those intersections and you'll be making adjustments automatically before you know it. :)
It's a great little machine and the cabinet is going to make a huge difference for you. I can't even imagine how someone can do FMQ when their machine is moving right along with the quilt. That would be so hard to get used to! I LOVE my "tank" machines with big heavy wooden cabinets! :)
Have fun! :)
