Lang Reinforcing Thread
Lang Yarns Jawoll Reinforcement Thread is perfect for adding strength to high impact areas of socks. Simply hold it together with your main yarn to reinforce toes, heels, and anything else needing extra strength.
Reinforcement thread is also a good option for seaming and attaching buttons when the main yarn is fragile or bulky.
