How to Long Tail CO (CO) in Knitting
The Long Tail Cast On (CO) is one of the most versatile and widely used cast-on methods in knitting. It creates a neat, elastic edge that works beautifully for everything from ribbing and hats to scarves and sweaters. Once you learn the rhythm — estimating your tail, creating loops with your thumb and finger, and pulling yarn through — it becomes one of the most reliable and comfortable ways to start almost any project.
While it might feel a little tricky the first time, the long tail cast on quickly becomes second nature as you practice it. The resulting edge is clean, flexible, and strong, which makes your knitting look intentional right from the first row. This guide walks you step by step through the long tail method so you can start your next project with confidence.
