Here's what is on the loom:
Can you see the circles? I didn't think circles were possible with four shafts:
The lower right corner sample is with the green weft on top and gold weft on the bottom layer, which give gold circles on a green field. I like that sample best, but it's almost impossible to see errors during weaving. The fabric to the left side shows green circles on a gold field, which is the reverse side when the gold weft is on the top surface and the green weft is on the bottom surface. That little wedge of gold in the top right is what I see during weaving. It's also visible on the right in the photo above this one.
If you click for big, you can see the ply twist in the yarns...fascinating stuff for handspinners. The yarn is 5/2 pearl cotton.
This is just the sample. I have enough warp to complete a table runner (if my vision holds out!) Perhaps I'll do another one with different colors and more value contrast.
