Handmade from 100% cotton. This swaddle blanket is thin, very lightweight, and breathable. It will soften significantly after the first few uses and washes. Easy to care for, machine wash in cold and dry on low to medium heat. These measure approximately 47" x 47", big enough to cover a car seat. Many color options! If you would like to check color or fabric quality in person before purchasing, fabric swatches are available for purchase in a separate listing.
