Great for sock toes, heels, cuffs, and colourwork where you just need a little bit of the colour, these teenie weenie balls of wool come in surprisingly handy. superwash, with nylon reinforcement, the wool pairs beautifully with most sock yarns and its tough durability and great colour selection makes it great as a mending yarn as well! 75% wool, 25% polyamide. 7 g / 13 m balls. Machine wash cool, dry flat.
