Stitch Shop Guide is a web reference site for sewing and quilting. Its tools include a bobbin and needle lookup by machine model and a needle size and type selector.
It also has shop pages that compare quilt shops, sewing machine repair, longarm quilting and classes in five US cities: Albuquerque, Colorado Springs, Knoxville, San Antonio and Tucson. A "How we check shops" page explains the methodology.
The builder wanted sewing machine references and researched shop details in one place.
