A much loved classic wool/nylon sock yarn by Lang Yarns:
50g /210m, as well as a 5g spool of reinforcing thread hidden inside the skein.
Fantastic for contrast heels and toes when knitting socks or for colourwork.
The matching reinforcing thread can be knitted in at points where you anticipate greatest wear, keeping your socks in tip top condition for longer!
A personal favourite of mine to use alongside my hand dyed sock yarns.
