just my two cents worth that every comment above is all true and correct! i also use my janome for quilting as well as just piecing and the thread just doesn't break at all using fmq compared to the other couple of brands that i have tried. i have spools upon spools of thread here that i bought 'on sale' and i just don't think i will ever use it. aurifil is definitely the way to go! i use it in hand sewing also.
