Congratulations. I hope you love it as much as I do. One of my favourite things about that machine is that if you have the needle down option engaged, a little tap of the presser foot makes it go up slightly so you can slide you work in and chain piece, hands free. it is a fantastic machine.
My fmq got decidedly better using the sensor matic feature.
i am happy for you that you got this machine, Grandma Mary!
