Yosef Karo

“ Similarly a Jewish craftsman is forbidden to make them for others, whether it is for money or if it is for free (Terumat Ha-deshen, Beit Yosef) , [nevertheless] the custom has become to be lenient with this, but if it is known and publicized that the work is for a non Jew, it is permitted (Terumat Ha-deshen) . Similarly the custom has become to give non-jewish craftsmen new items to alter during this time, inorder that they be ready after the fast, however it is good to minimise this activity where possible, as this is not prefreable from other forms of trade which we reduce. ”

“ Our method of laundry is permitted, but the Gihutz (ironing) (Explanation - We pass over the clothes a smooth stone, to smooth it. Aruch) that we do is not. For linen garments, there is no concept of Gihutz, so this is considered "our method of laundry," and permitted. But these words only apply for ironing it and putting it aside until after Tisha B'Av, but it is forbidden to wear it during that week. ”

“ We are accustomed to to be strict about all of this from the beginning of 'Rosh Chodesh' until after the fast, if it is not for the need of a Mitzvah, like a woman [at a time in her cycle] where she wears whites, and to arrange [the sheets] under her {to sleep on} (Rokach and the Ohr Zaruah) , but on Tisha be-Av itself, she should not wear whites, ratehr she should wear a garment which is clean and nice (notes of the Sha-a-rei Doorah) . Similarly for the honour of we wear linen garments and we arrange white [cloths] like on other Shabbatot. ”
