I've been spinning the fiber from a set of sample fibers that I bought long ago. The fiber came from Hood Canal Yarns, and there are some great exotic fibers and blends in it.
The fiber that I'm currently spinning is yak/tussah silk and the singles are spinning up quite nicely:
I'm going to navajo ply this as well. The singles are fairly fine, and it should make a nice yarn for weft.
I'm thinking that I'm going to weave a couple of scarves where I use all these samples up. I'll make them striped with different combinations of the sample fibers. Of course, that will be sometime after I've managed to spin them all.
I keep trying to plan my next weaving project, but don't quite get there. Maybe that will be tomorrow's project.
