This has become a batik discussion, not a Marshall's discussion, but I will add my 2 cents worth. We recently made a prayer quilt for the church which means it is a tied quilt. The needle with the 6 strands of embroidery thread went through the batiks easily, but had to be pulled through with pliers on the Moda white muslin.
Nothing I've ordered from Marshall's has been LQS quality, but certainly not bad and I like some of the patterns and selection of colors in a line. I don't have a picture of the quilt we made for the bazaar last year, but the Marshall's fabric in it certainly held it's own with the other fabrics used.
