Loom waste guide
Measure loom waste before it surprises your warp
Loom waste is the warp length that cannot become finished cloth. It depends on your loom, tie-on method, sampling, fringe, and how close you can weave to the end.
What counts as loom waste?
Include front tie-on, spreading waste, back tie-on, distance from apron rod to fell, and any warp you cannot weave because the shed is no longer clean.
How to measure your loom
- Warp and weave a normal project.
- When you finish, measure the unwoven warp at the front and back separately.
- Record the loom, tie-on method, and total waste.
- Save that number as a loom profile in the calculator.
Starting defaults
Use conservative defaults until you have your own data: about 24-30 inches for many rigid heddle projects and about 30-36 inches for many table or floor loom projects. Your equipment may differ.
