Underestimated

 I thought that I finally had enough of those blue striped singles to ply with the purple and yellow singles from the TdF.

It certainly looked like I had enough but....

 ...I was wrong. I still have lots of the original singles leftover.

 So now I'm back to spinning more singles even though I don't have anymore of the medium blue fiber. By the looks of the 2 ply, it really doesn't matter. As usual, it's not turning out to look anything like I expected but with this particular project, that's no problem whatsoever.
