This swaddle is our first original design! A lot of creativity, work, love and joy went into the design and production of this blanket. We are so proud of it! It is a large muslin/bamboo blend material which makes it soooo so soft and lightweight. When used as a swaddle it keeps babies warm yet the material is able to breathe. It is approximately 47 X 47 inches in size. The background color is white and the otter space pattern features soft tones of brown, blue, purple and grey to make it very gender neutral and beautiful!
