Rag rugs are not finished when you cut them from the loom. In fact, they can fall apart if you are not careful. A rag rug is not secure until warp ends are tied into knots. You need to leave space on the warp between rag rugs to make room for the eventual knots.
One way to leave space on the warp is by using warping slats as spacers. Simply weave about two inches of scrap header after the end of a rug. Then, insert warping slats in alternating plain weave sheds. And then, weave another scrap header. Now, you’re ready to start the next rug.
I leave about eight inches (20 cm) of warp between rugs. This gives me enough length for tying the needed square knots. If you are leaving fringe, add enough to include the desired fringe length. When you insert the warping slats, keep them centered so that they can go around the breast beam and cloth beam without catching on the sides of the loom.
It is easy to separate the rugs after they are off the loom. Cut between slats using a rotary cutter, with a cutting mat underneath.
May you make the best use of your time and tools.
All the best,
