What types of crochet joining are there?

There are two main types of seaming you will encounter, and that is:

1. Joining with a crochet hook

These methods use crochet stitches to establish a connection between the pieces, but they can result in both flat and 3D seaming.

Basic stitch joins

Sometimes simple crochet techniques are the best choice to achieve good results, because you don’t need to learn anything new. Single crochet, slip stitch – that’s enough, so use it!

Decorative crochet joins

You can crochet a whole panel between the pieces, which has a pattern on its own, and that’s what decorative joins are about. They play the role as important as the pieces themselves, so that the final effect is very eye-catching!


These techniques require attaching elements to each other while you are crocheting them, and not afterwards! It’s a good choice for those of you, who don’t like working with lots of small elements, so look for JAYG abbreviation.

2. Joining with a tapestry needle

To achieve the most clean, or even invisible seaming, use tapestry needle and yarn. It’s much easier than it sounds, so don’t worry if you’ve never tried sewing in your life!

Can I only use it to join crochet squares?

Of course not! Whether you are working with triangles, hexagons, or other geometric figures, you can join them with most of these techniques. The only way in which it will differ is the place where the seaming lines cross – many techniques will be fitted only for two lines crossing perpendicularly.

What kind of yarn should I use?

The best practice is to use the same type of yarn you use for your project, but whether you want it to blend in or stand out in terms of color is totally up to you!

In this section I’ve gathered the best ways to join crochet squares, but the best part? They ALL come with free tutorials! You can always find them linked below the pictures, so make sure to save them up for later.


Basic Joining Techniques

Slip Stitch Join

Let’s start with one of the most basic stitches in our arsenal, shall we? Slip stitch, which I wrote about lately in my article about surface crochet, can work magic. In the example below you can see how Jennifer used contrasting yarn to connect two hexagons. This technique creates classic braid-like structure between the pieces, but it doesn’t add volume.

Single Crochet Join

If you are looking for something more eye-catching, spruce up your projects with easy single crochet join! This method is fantastic if you are going for very simple designs, such as the one you see in the photos. Even the plainest squares come alive with the texture this joining creates, so be sure to keep it in mind!

Flat Single Crochet Join

Bella Coco’s variation on the theme resulted in this lovely zipper-like join, but it looks even better when made with contasting yarn. Sarah uses UK terms, so her tutorial is called flat double crochet join. Please see my table of crochet abbreviations to make sure you won’t get lost in translation.

Join-As-You-Go (JAYG) Techniques

Join-As-You-Go Granny Square with Flat Join

Working with granny squares can be a lot of fun, but joining them is another story. What if you could join them as you go? Because you can! Edie’s tutorial will teach you how to attach one square to another while working its outermost row. Take a look at the photos to see what I mean and save it for later!

PLT Join – SC, Continuous JAYG

If this name is confusing, I feel you, because I had to read deep into Rachele’s post to get a hang of it. This join combines two methods in one, and that is: Pull Through Loop Join (PLT) and Continuous Join-As-You-Go, which is a little bit different than regular JAYG. This unique join works like drawing a line without picking up your pencil – clever!

Joining Elements with a Needle

Whip Stitch Join

Cute little dots of contrasting yarn and all the pieces joined very close to each other – it’s many crocheters’ dream join. It’s also one of the easiest ones, but it requires using tapestry needle. In the bottom photo you can see the way Sandra’s yarn goes through both squares, but it’s also interesting to see how all four squares meet neatly in the middle.

Mattress Stitch Join – Invisible Seam

Although these photos don’t show it clearly, mattress stitch join is definitely the one to know, because it’s invisible. Yes, it totally disappears, leaving your squares sit so closely together they couldn’t sit closer! This technique is also very satisfying, because first you weave the yarn in a certain way, and then pull it to “close the zipper”. Fantastic!

Decorative Joins

Celtic Lace Join

Decorative joining techniques work like an essential part of the project, so you can’t just change them to basic ones. If you do, you will loose all the lacy beauty such seaming adds to the project, so it’s quite pointless. Rachele used her stunning join in a blanket pattern, and you can see how nicely it contrasts with solid textured and colorful squares.

Mijo Granny Join

Good crochet join should harmonize with the stitches used in the individual elements, and this example shows exactly that. Mijo Crochet’s join grows out of granny squares, repeating their last round, but then transitions into simple lacy pattern. As you can see in the top photo, the place in which all four corners meet looks like it couldn’t possibly be designed in a different way.

Scallop Join

There are many ways to join crochet squares, but this one definitely combines simplicity with a stunning effect. Gourmet Crochet’s scallop join is very easy to learn, so it’s a great choice for beginners who look for more than basic stitches. Lacy join adds lightness to the project, so keep it in mind when working with solid squares!
