I'm in awe of all of you who are able to FMQ a full size or even larger quilt on a regular sewing machine. With the weight involved, how are you able to keep it continuously feeding through? How do you deal with the bulk? I find it difficult even doing FMQ on a lap sized quilt, in spite of using all the bells and whistles which are supposed to help with the friction issues. I have a quilting frame and setup, but it's in storage and inaccessable at the moment, and it'd be nice to use my small machine for some tops I've made recently. Thank you in advance to anyone who might have some expertise in this area!
