For my book I selected a number of colors from the brand Yarn and Colors. Would you rather crochet with Catania, Catona or Durable Coral but still want to stick to the colors as much as possible? Then you will find replacement color numbers here. By the way, you can crochet with any yarn from 50 grams - 125m and you can even mix different brands, as long as it is 50 grams - 125m.
