I have just very,very recently started to do FMQ. I watched hundreds of videos on YouTube and just decided to try it. I got the darning foot and had to use a darning plate as well. The very hardest part for me was gettin my tension right. Also get the machine quilting needles. Yep, there are needles especially for that. Keep your material moving and don't try to pull it too fast, your stitches will be really long. Above all it takes lot of practice and if you are like me lots of thinking about giving up. Keep on keepin on... Good Luck
ps... once you get started you will love it and time will fly by...
