I've found that the 301's really don't work well for FMQ, the angle of attach of the needle doesn't lend itself, IMHO, to consistency in stitch or motion. Most FMQer's, I believe, will agree with this. Though the machine does have a vertical bobbin, a "straight" up down motion will yield better results such as in the 15-91 etc. The needle, in my experience, gets hung up with the slanted attack in the piercing. I'm sure there are some who can do it, but I've tried with the 301 and it doesn't yield good results for me. For straight stitching, it does beautifully, but certainly not the first choice for FMQ.
