I used to buy some fabric on here from a gal who got her fabric from Marshall's and I thought it was inferior - coarse.
Marshall's is a fabric distributor that quilt shops, fabric stores, and upholstery shops order through the reps.
Marshall's sells poly, blends, flannel, wool, upholstery, fleece, all quality of cotton fabrics. You can find every level of fabric quality there. I buy Robert Kaufman, Riley Blake, Red Rooster, Kona, Timeless Treasures, Free Spirit, Benartex, Michael Miller, Alexander Henry, RJR, and all the other name brands of fabric except Moda. Marshall's has Hoffman Batiks too. Marshall's has Quilters Dream solids that is excellent quality.
