Joining Crochet Squares Together 3 ways – Single Crochet, Flat and Slip Stitch Join

In this post I want to share with you all about joining crochet squares together! I am not a fan of sewing my crochet work together, so I wanted to talk about how you can crochet your motifs together and make life easier for yourself.

Not only do I find working a crochet seam to join motifs easier, I think it looks better too!

Each of the three methods I’m going to take you through have a different look and feel to them and are great for different things. Always good to have options don’t you think?

You can use these methods with the right or wrong side of your work showing, totally up to you. I mostly like to do it with my right side showing, as it adds a little interest and texture.

If you want a really flat neat look to your project I suggest working with the wrong side showing.

Be Prepared – what to do before joining crochet together

There are a few simple things you can do before you jump into joining your crochet motifs with whichever seam you choose. I promise the whole piece will look so much better for it!

  1. Block all of your motifs before you crochet them together – it will make sure they are all the same size and stop it from becoming ‘wobbly’.
  2. Check your stitch counts – make sure you have the same amount of stitches on each motif so they match up nicely.
  3. Lay all of your motifs out and decide on how you want them – there’s nothing worse than joining lots and then realising you did one wrong a few motifs back!

Once you have done all of these things you are ready to starting joining your crochet squares (or hexagons, or octagons, or whatever shape you have!).

So let’s jump into the 3 methods – the single crochet join, the slip stitch join and the flat crochet join.

1: Double Crochet Join (UK Term) Single Crochet Join (US term)

The single crochet join (or UK double crochet join) is a great crochet seam to add texture and make a project more robust if you think it needs it.

I often use this method on the right side of my crochet in the same colour as the edges of the motifs and it adds a really lovely ridge that is great fun!

My children love their blankets with this seam as it is really tactile and lovely to play with.

  • Yarn & Motifs


  • Crochet Hook


    Once you line your motifs/squares up, you will start at a corner (chain 3 in my patten). Insert your hook through both motifs in the last chain in your corner, attach yarn and chain 1.

    Then work a UK Double Crochet or US Single Crochet in that same stitch.

    Next you will insert your hook through the back loop of the next stitch on the first motif and the back loop of the second motif and create a UK Double Crochet/ US Single Crochet.

    For each stitch, you will insert hook through the back loop of the first motif and front loop of the second motif creating a UK Double Crochet/ US Single Crochet.

2: Slip Stitch Join

I love the slip stitch join as it’s so quick and easy! It looks great in a contrast yarn colour and adds a little texture to the fabric but not too much so is a more subtle option than the single crochet join above.

This type of seam is great for adding a little bit of flexibility and ‘give’ to a crochet project I find.

I generally use this for seaming crochet garments together on the wrong side so that the seam isn’t visible and it also isn’t too bulky on the inside when you’re wearing it.

It also works really well for other projects like bags and cowl or hats that are worked flat and then joined to a round. I have also been know to use it to seam my knitting projects together too and it works beautifully!

  • Yarn & Motifs


  • Hook


Working with the wrong side facing each other-

Line up your motifs and just like in method 1, we will be working in the back loop of the first motif and the front loop of the second motif.

Attach yarn to the corner, pull up a loop.

Insert hook through the back loop of the next stitch in the first motif, and the front loop of the next stitch of the second motif. Slip stitch.

Keep repeating this last step for each stitch, and try to keep your tension loose while doing these slip stitches so your seam is not too tight.

3: Flat Crochet Join

The flat crochet join is my favourite seaming method I think because of how neat and tidy it looks and how, well, flat it is!

I love to work this method on the right side of my crochet but it looks great on the back too in a contrast yarn or a co-ordinating yarn.

It’s amazing how you can completely change the look and feel of a finished object by choosing a different colour yarn to join it together with!

This crochet seam method does take a bit of practise as you are inserting your crochet hook into both sides one after the other but after a bit of repetition you’ll be an expert at it.

  • Yarn and Motifs


  • Hook


Line up your motifs, and like the other two methods we will be attaching our yarn at the corner.

For this method you have to be sure to insert your hook on the same side every time, and be sure to keep your yarn under your motifs.

I start on the right side, insert hook into the back loop of the right motif, and the back loop of the left motif, create a slip stitch.

Keep repeating the last step for each stitch.

If you want to check out the full step by step tutorial for these three methods you can find them on my Youtube Channel.

I often get asked what yarn and hooks I’ve used in my tutorials. In this one I used Drops Cotton Merino yarn and my White and Nickel Odyssey Furls Crochet Hook.
