Embroidery meets weaving = darning. But if you don't have a hole to mend, it's a decorative technique.
Make a rug loom with PVC pipe. Weave around top/bottom and sides of PVC to keep the weaving from pulling in. When done, just take apart the PVC and slip off the rug. What a great idea from Pink In Mind.
I wove this pattern on an 8 harness loom. I can't imagine doing it on a rigid heddle loom.
