I quilt with my Featherweight, but I have yet to FMQ yet though I've practiced a bit. I think it will be some time before I FMQ because I've been told that I can only FMQ for short periods of times or the machine can overheat. And so far I'm terrible at it.
I do use a walking foot. While my husband made me an extension table, it's still very difficult to quilt within the small throat space. (I've struggled through several queen size and one king size quilt.) I'm looking to cobble together a weightless suspended quilt frame - there are a few available commercially and DIY info online. Has anyone used one and found it made a difference while quilting? My arthritic hands need some help!
