You can never have too many bags ... and this one will quickly become one of your favorites! It's a cute, roomy, easy to carry, self-closing style that doesn’t even need a lining. Knit in one piece, the body of the bag is felted in the washing machine. The long strap is knit flat or in the round and encases a soft cotton cord for added strength and comfort. The strap is lightly felted by hand, and hand stitched to the felted bag in two places. Try it—you’ll love it!
