Reinforcing thread

For all of you sock knitters out there, we’ve got another oft-requested item! Reinforcing thread! What do you do with it? You run it alongside your sock yarn in toes and heels, to make them stronger and give them a longer life.

Each little spool is 5 grams, and has 75% superwash wool, 25% nylon. They retail for $3.50 each, and come in a wide range of neutral-y colors that would go with pretty much any sock yarn out there!
