Lithuanian linen is machine washable; for the best care please wash them individually using cold water no more than 40-degree celcius. Wash gently on a slow cycle, and please use mild, liquid laundry detergent to not compromise its quality and keep in shape. Do not bleach.
Air drying is preferable for linen, but if you use a machine dryer please tumble on a low dry heat and remove promptly afterward. Avoid personal skincare containing benzoyl peroxide.
Linen will shed at first since its natural fiber - this however stops after a few washes eventually.
Linen does not need ironing since it has achieved that 'natural look' but if you like more structure and feel - iron with low/warm heat on 'linen' setting.
