As with any textile product, whether linen or clothing, it is recommended that products are always washed before first use, even for GOTS organic cotton products dyed with GOTS approved safe dyes. This is because the textile products are made by hand and sewing machines (overlockers) create a fine cotton dust when cutting the excess fabric from the hems. It is therefore always recommended that you wash your textile products before using them, for reasons of hygiene.
