This fiber is absolutely wonderful. It is 19 microns and is a pure white. Nylon is probably the best blending fiber out there, especially if you want to add some strength and some stretch to yarn like sock yarn.
This listing is for 8oz.
Snow Mountain Nylon also is known for its amazing ability to take dye - it literally sucks up the color and can be dyed any color you can imagine.
You can spin this fiber on its own for a lovely yarn or spin it and ply it with something like merino. You can also take small amounts of it and blend it with any fiber you can think of for a fabulous sock yarn blend.
