Na Dannsairean "Colour" is a 4ply yarn made up of 85% Merino, 25% Donegal Nep, which is a nylon fibre. The Neps are brightly coloured on this base. There are approx 400m in each 100g hank of yarn.
Please be aware that one of the appealing aspects of my hand dyed yarn is that it is not an absolutely solid colour throughout the hank. There are variations of shades.
