Black and white are more than just design choices. High-contrast, black and white patterns enhance baby's vision and stimulate brain development. Modern Burlap continues the tradition of our signature, black and white muslin swaddle blankets with the introduction of our GOTS certified organic cotton muslin swaddles that are both eco-conscious and gentle on baby's skin! Every blanket is pre-washed, breathable, versatile, and ultra soft, becoming even softer with each use and washing.
