This is a Batt in a Braid: this series is a set of custom-designed blends made to be as complex as batts, but in "braid" form - hence the name :-)
It's easier to remember by number than by a whole string of ingredients ...
This blend - Batt in a Braid #43 - is made up of:
60% Dorset 20% Cheviot 20% Kid Mohair
This custom blend was designed for spinning sock yarn. Both Dorset and Cheviot fall into the category of Down (or Down-like) breeds; as such, they are naturally resistant to felting, whilst the Kid Mohair adds a bit of strength and helps to produce rich colors when dyed.
I take great care to make sure that dye is sufficiently exhausted and heat set the fibers so there is minimal to no run-off. However, due to differences in water across the globe, what runs clear for me may bleed a little for you. Please take care to hand wash your finished item in cool water and lay flat to dry. I also make every attempt possible to use a photograph that is as true as possible to the real color. Monitor settings may vary.
