Well, I knew it might happen sooner or later. I put a four towel warp on the warping board and I am just a few inches from finishing when I ran out of the Webs Valley Yarn 8/2 magenta. I need about six "passes" on the warping board of this color, but it looks like they don't carry that color number anymore, but they do carry the color number in their 10/2 mercerized cotton. if I need so little of this color, can I mix the new 10/2 mercerized with the old 8/2 unmercerized? I feel that I could, since so little is needed. What do you think?
