I am at a Fiber Sorting/Grading Seminar led by Course Broads, Inc. I am going to learn how to properly sort and grade alpaca fiber for mill and for show fleeces plus I am going learn all there is to know about the micron of fiber. What is Micron?
I am copying this from Yocum McCall, where I get my fiber tested each year. It's copyrighted but I am giving them credit so...I think it's ok. I hope it's ok. Here it is, so it must be ok.

Fiber Diameter Measurement and Distribution
Fiber diameter is measured in microns. One micron is equal to 1/1,000,000thof a meter
or 1/25,400th of one inch. Mean Fiber Diameter (MFD) is in common use internationally.
MFD, Standard Deviation (SD) and Coefficient of Variation (CV) all relate to the
(approximate) normal distribution of the animal fiber diameters. SD characterizes
dispersion of individual measurements around the mean.
In a normal population, 66% of the individual values lie within one SD of the mean, 95%
within two SD's and 99% within 2.6 SD's. Since SD tends to increase with increasing MFD,
some people prefer to use CV (=SD*100MFD) as a method of comparing variably about
different sized means.

It's a long-winded explanation but it is complicated.
At the end of this seminar, I will begin my journey to become a certified grader/sorter. What does this mean? Well, farms will be able to hire me to come sort their fiber for mill processing. I will have the ultimate understanding of what I am doing with my fiber which will help in my fiber production and my farm's breeding decisions.
It won't be all fun and games. There is a lot of study involved. I will have to sort an insane amount of huacaya and suri fleeces in the next year so neighboring farms will have an opportunity to get their fiber sorted/graded at a discount.
Next week I will have tons of information and pictures to share with you. Until then, please enjoy my new Fiber Arts Friday Buttons. I have one at the side of my page and here are a couple more.
Now, I want to hear what you have been doing all week. Share your adventures in fiber arts!
