I do mainly machine piecing and hand quilting. The hand quilting thread often is stiffer to allow something that thick to fit through the teeeeeeny tiiiiiny eyes of hand quilting needles. The extra starch would not work for any kind of machine I've owned.
Lately, I've been seeing beautiful machine quilting thread, colors and variations not available before, so I may have to find a quickie project just to try them out. The beautiful shiny rayons I've used for machine embroidery, and metallics for crafts. The special needles required are kinda pricey, but worth it for the troubles they avoid.
