If you knit long enough, you’ll face it—your ball of yarn is running out and you’ve still got rows to go. Whether you’re switching colors, starting a new skein, or fixing a break, knowing how to join yarn in knitting is a skill every knitter needs. The good news? It’s easier than you think, and there are several ways to do it neatly, invisibly, and securely.
This article will walk you through different yarn-joining techniques, when to use each, and how to make your transition so smooth, no one will even notice it happened.
Why Do You Need to Join Yarn?
It’s not just because your yarn runs out. You might also need to:
- Switch to a new color
- Change yarn weights or textures
- Fix a snapped strand
- Start a new skein mid-row in larger projects
Regardless of the reason, the goal is the same: a seamless, strong connection that won’t unravel and won’t leave an ugly knot in the middle of your beautiful work.
Best Times to Join Yarn
Before we get into techniques, here’s a tip that can make all the difference: try to join yarn at the edge of your work (like at the beginning of a row) whenever possible. This makes weaving in the ends much easier and keeps the join hidden.
That said, many joining methods can be used mid-row without anyone noticing. So don’t panic—just pick the method that suits your yarn and project.
1. Overlap Method – Quick and Easy for Beginners
This is the simplest way to join yarn mid-project and works great for stockinette, garter stitch, and simple patterns.
How to do it:
When you have about 5–6 inches of yarn left, lay the new yarn alongside it and knit 4–6 stitches holding both yarns together. Continue with the new yarn, and later weave in the loose ends.
Best for: Beginners, acrylic yarns, or when you don’t mind weaving in a couple extra tails.
2. Russian Join – Almost Invisible!
This is a favorite among knitters who want a smooth, knot-free finish. It’s great for slippery or thin yarns and ideal when you’re using a single color for a long time.
How to do it:
Thread your yarn onto a darning needle. Insert the needle back into the strand, weaving it through itself for about two inches to make a loop. Do the same with the new yarn and pull them through each other’s loops. Tighten and snip any extra fuzz.
Best for: Smooth, seamless projects like shawls, sweaters, or anything where bulk matters.
3. Magic Knot – Strong and Fast
This method gives you a super-strong connection. Just be aware that it can leave a small bump in fine fabrics.
How to do it:
Tie the old yarn around the new yarn, and the new yarn around the old yarn. Pull the knots tight until they lock together. Tug on both strands to test the knot, then trim the tails close to the knot.
Best for: Colorwork or durable projects where the slight bump won’t matter (like socks or blankets).
4. Spit Splice (aka Felted Join) – For Wool-Lovers
If you’re using 100% wool or other animal fibers, this is the join for you. It requires no knots, needles, or weaving in. Plus, it’s fun!
How to do it:
Fray the ends of the old and new yarn slightly. Wet both ends (with water or, yes, spit), overlap them, and rub between your palms until the fibers fuse. Let it dry for a second, and you’re good to go.
Best for: Pure wool yarns and feltable fibers. Don’t try this with cotton or acrylic—it won’t work.
5. Tie-and-Weave Method – Basic but Reliable
This one’s simple: just tie a small knot, keep knitting, and weave in your ends later.
How to do it:
Tie a square knot or double knot where the yarn changes. Keep the tails at least 6 inches long. After a few rows, go back and carefully weave in the ends using a tapestry needle.
Best for: Quick joins when you’re in a rush or working on non-showy areas.
Bonus Tip: Don’t Panic Over Yarn Tails
After joining yarn, don’t trim the ends too short right away. Leave at least 5–6 inches of tail so you can weave them into the back of the fabric. This secures the join and keeps your work tidy.
Also, try to weave in the ends in a zig-zag motion through matching stitches to avoid lumps and bumps.
Which Join Should You Use?
| Join Method | Best For | Looks Invisible? | Durable? |
|---|---|---|---|
| Overlap Method | Beginners, everyday projects | Mostly | Yes |
| Russian Join | Lightweight, smooth yarns | Yes | Yes |
| Magic Knot | Strong color changes, quick fixes | No | Very |
| Spit Splice | Wool and animal fibers | Yes | Yes |
| Tie-and-Weave | Simple or rushed work | Depends | Yes |
In Conclusion
Learning how to join yarn in knitting is a game-changer. Once you master even just one or two techniques, you’ll feel more confident tackling larger projects and color changes without fear of messy transitions or unraveling.
The best method depends on your yarn, your project, and your comfort level. Test a few out and find your go-to favorite. With a little practice, your yarn joins will be as flawless as the rest of your knitting.
