thousands and thousands of quilters do not have a long-arm---
and thousands of quilters who make fabulous large quilts- sell patterns, books, travel the world teaching- do not own a long arm- they quilt on their domestic machines, hand quilt & send out their quilts to their favorite quilters-
not everyone even has any interest in the quilting part of creating quilts- they like to piece, create tops- owning a long arm is a minority market.
