One more thing about temples and croc clips!
Devices that deal with too much draw-in
If everything about your cloth is just as you want it, but the draw-in is causing the selvedges to break. You can stretch out the warp near the reed so the reed can’t abrade the threads while weaving.

Temple
A temple is a stretcher that holds the cloth out at the selvedges.
See Figure 529. It allows you to snug the wefts up to the selvedges without breaking the threads during weaving. It may be made of wood or metal. Any temple needs to be
strong. They are available in many widths for weaving wide rugs or narrow placemats.
Cord and clip stretchers

This stretcher is a variation of a temple that you can make yourself. See Figure 530. The clips are “Crocodile clips” (also called “croc clips”) and are available at hardware stores. They are made to clip tarps and are very inexpensive.
This information is from page 312 in my new book, “Weaving for Beginners” in the chapter on selvedges. For more information, see the tip: “Using a Temple or Stretcher“.
