We recommend that you unfold the product completely before washing and avoid overfilling the machine. The product stretches easily after washing. The bedding can withstand being tumble-dried at low heat, but we recommend that you air dry the bedding, as it gives a smoother result and is better for the environment. The first times you wash your bedlinen, we recommend 40 degrees and you may experience some creasing. Since the bedding is 100% organic and without any anti-crease chemicals or other synthetics, it will have a natural crease, but it will be smoother in use when the fibers have been processed and settled. If a smooth and shiny look is desired, ironing is recommended.
