Tie the heddles (string loops) that hold the alternate warp threads.
With your right hand, pull up on the warp threads behind the heddles to make the first opening.
an inkle loom * a shuttle, or flat stick, to hold the weft, or crosswise threads * two sticks, like popsicle sticks, to use as the warp sheds, or opening for the plain weave * a scissor * cotton carpet warp or string for the heddles, or string loops that hold the alternate warp, or lengthwise threads * inexpensive, strong, smooth, colorful threads (a minimum of six different colors) - either carpet warp or pearl cotton
Rigid heddles can be easily made from popsicle sticks.
The second student of the pair holds the rigid heddle and the already-threaded warp threads, while the first feeds the new warp threads into the rigid heddle: hole, slot, hole, slot, etc.
Next, the student holds the threaded rigid heddle with one hand and the warp beam with the other.
