How to Join Yarn with the Spit Splice

Balls of yarn aren’t endless. At some point, they run out.

When that happens, you’ll need to join a new ball of yarn to keep knitting.

Just as there are many roads to Rome, so too are there many ways to join yarn together.

The spit splice is one of those handy and slightly weird knitting hacks that seamlessly joins two strands of yarns together. The join is permanent and doesn’t require weaving in any yarn ends.

What makes it unusual is that it uses spit, as its namesake suggests, to get the job done.

In this post, I’ll show you step-by-step how to join yarn with the spit splice, along with some tips and tricks to help you get a perfect join.

What Yarns Work with the Spit Splice?

The spit splice works with animal fibres only. Meaning, wool, alpaca, mohair, camel and cashmere fibres can be joined beautifully.

On the other hand, synthetic and cellulose fibres will not work with the spit slice. So, if you’ve got acrylic, polyester, cotton, linen or flax yarns, you’ll need to find another joining method (like the Russian Join for example).

Advantages of the Spit Splice

Unlike a traditional join, which includes weaving in the ends of both the new and old yarns into the knitting, a spit splice is seamless.

Because both new and old strands of yarn are felted together, the join is very strong.

Lastly, a spit splice creates a neater join than the traditional method. Because there are no ends to weave in, there are also no ends that will poke out from the knitting.

Step-by-Step Spit Splice Tutorial

1. Untwist the Yarns

Untwist about 3 inches of each yarn strand. Loosen the plies on the yarn and slowly untwist them.

The yarn strands will look fluffy like crimped hair when they are un-plied.

2. Overlap the Yarns

Overlap the two strands of un-plied yarn.

3. Get Your Spit Involved

This is the potentially gross part. But I’ve got a couple options to make it less gross.

a. Put the overlapped yarn strands in your mouth and slobber all over it, like a dog with a bone. Cover both un-plied strands with your saliva (Gross Factor: 5/5)

b. Place the overlapped yarn strands on a plate and spit on them, covering both strands (Gross Factor: 3.5/5)

c. Dab a bit of warm water all over the overlapped yarn strands. While water will work, I personally find that saliva provides a sturdier join (Gross Factor: 1/5)

4. Rub-a-Dub-Dub

Lay the overlapped yarns on your palm. Then lay your other palm over the yarn, sandwiching it between your hands.

With the two un-plied yarn strands sandwiched in your hands, begin rubbing your hands together vigorously.
