We have tried: We washed the material at 30 °C / spin 800 rpm - there was no need to iron it. It shrunk by 2% in length, it did not shrink in width. Despite the lower shrinkage, it is strongly recommended to shrink the loneta fabric before sewing (wash at the temperature that you will use later when washing the sewn product normally, usually 30 °C or steam it thoroughly with an iron) to prevent shrinkage of the sewn product.
The fabric measurements needed for sewing basic garments and home textiles, can be found here .
