Earlier in March, I spun up a Yak bundle that I picked up over at Stitches West this year.
It included three 1-oz bumps of:
* brown yak
* yak merino
* tussah silk & yak
I had trouble with Yak before, and I wanted to get some practice in before spinning up my other yak merino bumps from Abstract Fiber.
So, I pulled out my Ashford Kiwi and set it to a ratio of 14:1. Because yak has such a short staple length, I also criss-crossed the fiber across the flyer hooks so I could get more twist into the fiber before it went onto the bobbin. This worked really well. (Tip learned from one of the Ravelry forums)
The simple brown yak proved the most problematic for me, because of the short staple length. The yak-merino was only slightly better, with the merino adding a little bit longer staple.
The tussah silk/yak had its own challenges. The silk added much needed staple length to the yak, but I don't think it was well blended. I would get areas were it was obviously only yak and so had similar problems with the simple brown yak.
After spinning all 3 bumps, I:
1) spun a 3 ply from each bump - 60 yards
2) spun a 2 ply (yak-merino & tussah-yak) with left overs from Step 1) (14 yards)
3) navajo plied the remaining tussah-yak (14 yards)
Of course, with only 87 yards, this doesn't leave me much to work with, so I'm planning on picking up some matching solid yarn to hopefully incorporate making a very very warm hat for someone.
