I dyed some fingering weight Superwash Merino and Nylon yarn in the colour from Day 12 of 2018's yarn Advent Calendar. It is called Mid-life Crisis and it is a semi solid blue with teal and black splotches and speckles.
If you're looking for yarn to pair with Mid-life Crisis try: Lucy in the Sky, Self Reflection, or Because - colours 9, 10, and 11 from the Advent Calendar.
80% Superwash Merino wool, 20% nylon
Although superwash wool is machine washable, for best results I recommend handwash cool, dry flat.
The cost is for one skein though multiples may be available - please select your quantity from the drop-down menu.
