Beginning to weave the "pebble" bag

I've finally begun to weave the bag. I keep the inspirational pebble close at hand while weaving freeform meandering weft in a variety of greys and a bright white. Every weft is made up of three strands to keep the texture and colours rich.The greys are all done in even weave, but the white has a combination of even weave and rows of "over two, back under one" stitch to increase the intensity.
