You can't really see that it's a double weave while it's on the loom like this, but believe me, there's another layer of weaving underneath!
It's been threaded up as block weave and this exercise is mainly to demonstrate the arrangement of the blocks in a kinetic design. In the next exercise I will separate the coloured blocks with strips of the darker colour on the top of the weaving. The back will be the reverse. The instructions after that are "play"! We have a spare week before our next class, but I also have the Summer and Winter block weave to complete, so I'd better keep track of my time.
