Ma Lin held the spool and led a transverse thread, threading it through the middle of two layers of longitudinal threads, then used the 'heddle' to push it towards Ma Lin's side, making it tightly align with other transverse threads, leaving very small gaps.
Auntie Tao set the movable crossbeam to the lowest position, thereby lowering all the odd-numbered longitudinal threads to the lowest point, beneath the even-numbered longitudinal threads, allowing all the longitudinal threads to complete the cross-weaving with this transverse thread.
The longitudinal threads were still divided into two layers, with a large space between them, so Ma Lin could hold the spool again and pull another transverse thread through the middle, then use the 'heddle' to push this thread to Ma Lin's side, arranging it closely with the previous longitudinal threads.
