I have never heard of a longarm referred to as a "home machine". The regular sewing machines such as Singer, Bernina, are usually called Domestic Sewing Machines.....or DSM. The "home machine" category IS confusing. Maybe they're trying to separate the "home longarms" from the "professional longarms". There SHOULD be a separation for this.....also a separation from the quilting being done with a DSM versus a longarm, IMHO. I thought it a shame at one show where a friend lost out on her quilt which was outstanding in the piecing/colors to a so-so quilt that won because the longarming had been done by a fantastic longarmer.
