Approx 25gm/100m mini hanks of undyed 75% soft merino plus 25% nylon yarn.  These are excellent for using between the shades in a fade set or for cuffs, bands, toes in socks.  
This yarn needs to be washed before using to ensure it has 'plumbed' up to ensure tension will be the same as the same yarn already dyed.
Soak in cool to warm water for 30 minutes in the hank.  Squeeze out excess water and dry.   It is then ready to use.
Recommended needles 2.5mm- 3.25mm (after yarn is washed) or size to meet gauge of pattern.
Gentle machine washable.  Dry flat and in the shade.
