The wound bobbins are slotted onto rows of pegs on an upright frame called a creel; the threads are drawn towards a reed and individually entered by hand through the comb-like structure, keeping each thread separate. Once all the threads are ready, they are tied to the warping mill; this revolves, winding the threads around its 5-yard circumference in a narrow section as many times as the length of cloth demands; so a 63-yard fabric will require 13 revolutions of the warping mill.

The warper ties off the threads and moves the process sideways to build up the next section of the warp, adding section by section across the width of the warping mill until the required number of threads is achieved, which can be up to 14,400 on warps for our Pressure Harness looms. Once finished, the warp is wound onto a warp roll, in a process called beaming off.
