These tiny, perfectly formed 10g balls of mercerised cotton have become Instagram stars in their own right thanks to their downright cuteness. With 25m/27yds of yarn in each ball and available in 100 pretty colours they are perfect for small projects such as decorations or amigurumi – although we know quite a few crocheters who simply display them in jars like sweets! Win the entire set of 100 balls, thanks to our generous friends at Yarn and Colors!
