I just bought this machine... started using it on Monday and LOVE it! I don't know how to FMQ yet but I've quilted two Project Linus quilts using the walking foot this week and am going to start playing around with FMQ next week.
The thread cutter is amazing, I love being able to adjust the pressure foot pressure (it just cruises through all layers when sewing down binding) and it is FAST. I did about 35 string blocks the 1st 2 days just to get used to the knee lift & thread cutting using the heel of the foot pedal. I had the speed on "rabbit" setting and it flew!
I am happy to answer any questions.
