ALL CANVAS BAGS ARE NOT CREATED EQUAL: At Wm. J. Mills & Co., they craft their canvas bags one at a time in their sail loft with the same meticulous attention to detail that has served as their hallmark for over a century. Their master sewers make each bag their art. Each of their hand-crafted canvas bags is created using the same rugged fabric and stitching used to make their weather-resistant marine products and awnings, so you know that theyâ€™ll last, year after year. Plus, they employ â€œdouble-needleâ€ stitching to create rolled and finished seams â€“ inside and out â€“ for unsurpassed strength and longevity. Timeless style, built to last a lifetime. At SINGER22 you will find a selection of Wm. J. Mills & Co. duffles made exclusively for us.
