Insert a fourth stick into the shed of the same row and slide the top one to the top of the warp and the lower one to the bottom as before. These two basic rows are repeated alternately to form the sprang. On the fifth row the first two sticks you inserted withdrawn from the warp and reused in successive rows, and soon, always taking the sticks from the extreme top and bottom of the warp.
The sticks serve a two-fold purpose, enabling the threads to be beaten up and down after each successive row thereby maintaining the tension, and allowing mistakes to be rectified by undoing the rows - to do this remove all sticks from the current shed and undo by sliding the sticks from the previous row towards the centre which will undo the interlinking. Continue back to the mistake and re-warp.
