Dhaka cloth can be woven with the pattern threads inlaid along with a ground weft thread, or only using only pattern threads in the weft, which produces an effect like tapestry. As far as I can see, this weaver was using the second method, twining each weft colour around it’s neighbour to avoid producing holes in the fabric. The design in purple, blues & peach is mountains and forests.
