4.1.8

tantuvāyā daśaikādaśikaṃ sūtraṃ vardhayeyuḥ //

Weavers shall increase the threads (supplied to them for weaving cloths) in the proportion of 10 to 11 (dasaikádasikam). They shall otherwise, not only pay either a fine equal to twice the loss in threads or the value of the whole yarn, but also forfeit their wages. In weaving linen or silk cloths (kshaumakauseyánam), the increase shall be 1 to 1½. In weaving fibrous or woollen garments or blankets (patronakambáladukúlánám), the increase shall be 1 to 2.
