✔️ Choosing the right yarn weight is essential for your project to have the correct finish, texture and measurements. The weight defines the size of the needle or crochet hook you should use and directly affects the gauge, drape, volume and density of the fabric. It also influences the amount of yarn you will need and the time it will take to complete the project. Using the correct weight is key to ensuring the result matches the pattern and achieves the look you want.
