This is a wonderful warm two-ply yarn, handspun and hand-dyed by Lanifica. The soft, springy merino was spun using a drop spindle and dyed primrose yellow using organic turmeric root and an alum mordant. Unlike most dyes, it smelt delicious! You can see several photos of the dyeing process on the shop tumblr (eg. http://lanifica.tumblr.com/post/172106683217/a-blender-would-definitely-be-easier-maybe-i)
Five 100g skeins are currently available. I class it as laceweight at 22 WPI.
Please note that colours may look different on different monitors. Additionally, turmeric (like most natural yellow dyes) is liable to be fugitive: the colour will fade after washing and exposure to the sun.
