Yak Fiber Study

Kat Tylee, owner of Little Hawks Yarns and a fiber judge at the USYAKS Show at the 2020 National Western Stock Show has designed a scientific study of yak fiber. Specifically her goal is to do a four year study (2020-2023) to measure the diameter and obtain a full histogram of the fiber of at least one hundred yaks from the yak herd in the United States. During 2020 she has obtained samples from 23 yaks and as the 2021 combing commences she hopes to get the other 70+ samples.  

Sample Collection: Collect fiber by combing. Fill a snack-sized baggie for each yak you are collecting from. Label each bag so they can be identified with the correct yak listed on the Fiber Testing Form.

If you would like to participate in the study please complete the Yak Fiber Testing Form and send the form with the collected fiber samples to:
