Running out of yarn mid-project? Or maybe you’re switching colors? Joining yarn in crochet can feel tricky, especially if you’re new to it. But with a few simple steps, you can make smooth, strong joins that won’t unravel or stand out in your work.

Whether you’re joining the same yarn or adding a bold new color, these steps will help you keep your stitches clean and your project looking great.
Step 1: Know When to Join

Try to join yarn at the end of a row or round whenever possible. It helps keep the joint less noticeable. If you must join mid-row, aim for a spot where it won’t be too visible, like the side or bottom of your project.
Step 2: Leave a Tail

When you reach the end of your yarn, leave about 6 inches of tail before cutting. You’ll use this later to weave in and secure the end. Do the same with the new yarn you’re adding — leave a 6-inch tail to work with.
Step 3: Overlap the Yarn
Hold the old and new yarn together for about 3–4 stitches. Crochet over both yarns to make a smooth transition. This not only hides the join but also helps secure it. This works well for color changes too!
Step 4: Keep Tension Even

As you crochet over the joined yarn, watch your tension. It’s easy to pull too tight or too loose here. Try to keep your stitches the same size as the rest of your work for a seamless look.
Step 5: Weave in the Ends

When you finish the row or round, use a yarn needle to weave the yarn tails into the back of your stitches. Go in one direction, then back the other to lock them in place. Trim any excess yarn when you’re done.
