From Rope to Thread

This is 75% Black Welsh Mountain and 25% silk from Hilltop Cloud.  My singles have become more fine with each successive spindle, and this looks like thread.  I was worried that three strands of thread, plied, would equal a very thin, scratchy skein of yarn.  This came in at 15 wraps per inch (WPI),  a little thinner than what I want , but so very close to the yarn I'm aiming for, and it's not as scratchy as I feared it would be.  I'm very curious as to how this will feel, when it's knit up.
