The new warping board and stand makes winding a warp such a breeze that I was sort of disappointed to be finished.
This is approximately 250 threads and 8 metres in length.
The colour is closest to being like the first picture. It's primarily a vibrant yellow, but there is a fair bit of white as well and a sprinkling of green and a touch or two of royal blue. Still not sure about the blue. If it doesn't look right once I get the warp beamed I'll just pull it out and add supplemental warps of a softer colour.
The warp is mostly cotton with a few threads of synthetic novelty yarns. I'm participating in a weave-a-long in the "Weaving in the Saori Way" group on Ravelry. The intent is to weave yardage for some sort of summer clothing.
