Marcus Fabrics - New Aged Muslin - Hunter. The only thing better than our Aged Muslin in beige tones would be this same great look in cool blues and greys! They'll give an authentic look when paired with reproductions, or a casual tone when blended in with contemporary prints even with denim or chambray. We like them for the look we get when added to Japanese Taupes. From Marcus Fabrics of New York. 100% Cotton, 44/45in Wof.
