This pattern is great to show off a yarn that changes color especially when you wind it around your neck. Use the needle size that is recommended for the yarn or up to 2 sizes larger. The scarves shown are 3-4" wide and 60-76" long. If you want a wider scarf, the length will be shorter. You can use any weight of yarn and will need about 100g of the yarn you choose. Though i've specified worsted weight yarn below, you can use any weight of yarn.
