Invisible Seam – Joining You Crochet Hexagons Seamlessly
If you are looking for the perfect seamless invisible join for crochet hexagons, granny squares or other crochet pieces, this technique is the one you need. It’s simple, it’s quick, and will make your hexagons (or granny squares) look like they were crocheted in one continuous piece.
I recently updated my crochet hexagon pattern with brand new photos and a video tutorial and I’ve been crocheting a bunch of them for a new honeycomb baby blanket. I still have to decide which joining method will suit it best, but at least I have only two options left on the list: the invisible seam join and the single crochet join.
Today I will show you how to join your hexagons, granny squares or other crochet pieces with the invisible seam joining technique plus tips on how to avoid the corner gaps that usually occur.
I specialize in designing baby blankets and afghans and I often get asked questions about joining crochet motifs, the order in which they are joined, and how many you need to make a blanket. Here is the answer to the most popular ones.

When should I use the invisible seam joining technique?
- when you want your motifs to look like they were crocheted in one piece, seamless on both sides
- when you want a non-bulky join between your crochet pieces
- when you are piecing together a garment (joining arms to a cardigan or the skirt part of a dress etc)
Do I need to block crochet motifs before joining?
Blocking is not a must but I highly recommend you block your crochet pieces. Why? Because your crochet hexagons will have to be lined up so the stitches can match and blocking help by making them the same size, flat, and easier to handle.
Can I seamlessly join any crochet piece?
Yes, the invisible seam technique can be applied to any piece of crochet. You can seamlessly join:
- crochet hexagons, granny squares, or any other crochet motifs for baby blankets and afghans
- crochet garment pieces
- any flat crochet piece
- amigurumi toys and any 3D crochet piece
In what order I should join my crochet hexagons for baby blankets?
Joining hexagons to make a blanket is not as easy as joining granny squares because they have a lot more edges that don’t perfectly align. My method is to sew them in strips the length of the blanket I am making, and then join the hexagon strips with a continuous join. I find this technique to be a lot easier and less confusing.
How many hexagons do you need for a blanket?
I get this question a lot! There is no straight answer to it, it depends on how big your hexagons are and how big you want the blanket to be. You can get a rough estimate by crocheting one hexagon, measuring it, and then figuring out how many you will need for the width and how many for the height of the blanket.
Now that I’ve answered some of your questions about joining your crochet hexagons, let’s get down to the actual invisible seam joining technique!
Invisible Seam Joining Instructions For Crochet Hexagons, Granny Squares, etc.
For this particular tutorial I used crochet hexagons because I wanted to show you how I join them in the corners, but you can use these steps and tips to join any kind of crochet pieces together with the invisible seam technique.
• tapestry needle
• yarn in the color of your hexagons
TIP #1: make sure your pieces are aligned and the corresponding stitches are matching (the first stitch on hexagon 1 is in front of the first stitch on hexagon 2 and so on). If your stitches get out of alignment and you skip one (or sew twice in one) by mistake, you will end up with weird puckers and uneven angles at corners.
TIP #2: Use the same type and color yarn as your crochet hexagons. This will make the joining sewing stitches completely invisible. I used a contrasting color so you can see better where each stitch goes.
TIP #3: If it has yarn coming out or in of the stitch, move to the next stitch. You only want to sew through a stitch once.
TIP #4: It’s easier and you can see the stitches better if you hold two hexagons together with the wrong sides facing each other and sew them together like that rather than doing it on a flat surface.
TIP #5: Do small batches, don’t just sew through an entire crochet piece and then try to pull the yarn end. Instead, sew through a few stitches (or one side of a hexagon), then pull the yarn to join them. And then sew through a few stitches again and repeat the process.

Invisible Seam Crochet Written Instructions
We are going to join the hexagons by sewing through the middle of the stitches. Your needle will go through the middle of the stitch, between the front and back loop, from the top, all the way under, and back up the middle of the following stitch.
The starting point will be the corner of the hexagon and, to make the tutorial easy to follow, I assigned a number to each stitch. I also assigned a number to each of the 3 hexagons.
Stitch #1 is the chain in the corner, right before the double crochet stitches.
Step 1: Join the yarn to the hexagon
Pick up hexagon 1 and insert the needle into stitch #2, underneath and back up into stitch #1. You only go backward once, in the beginning, when you are joining a new piece of yarn.
Step 2: Align the hexagons 1 & 2
Put hexagons one & two together, with the wrong sides facing each other.
Step 3: Sew the stitches together in a zig-zag pattern
On hexagon 2, insert the needle into stitch #1 and back up into stitch #2. Move back to hexagon 1, insert the needle into stitch #3 and back up into stitch #4. Now go back to hexagon 2, insert the needle into stitch #3 and back up into stitch #4. Make your sewing stitches loose.
Can you see the pattern here? Keep alternating between the hexagons until you made your last stitch in the first chain in the corner (your needle will come out of it, not inserted into it).
Step 4: Tighten up the stitches
Place the hexagons on a flat surface. Your stitches will look like shoe laces (or corset lacing). Hold the yarn end at stitch #1 and slowly pull the yarn at the other end until the hexagons are joined together and you can’t see the joining yarn anymore.
You have now joined hexagon 1 to hexagon 2.
Step 5: Avoid corner gaps
When sewing a hexagon in the corner space created by two other joined hexagons, you will need to make one extra step to avoid the corner gaps that sometimes occur.
I have started joining hexagon 3 to hexagon 2 from the outer corner. Once I finished with that side, the logical thing to do is to start joining hexagon 3 to hexagon 1. But before you do that, do this extra step to make sure there are no corner gaps.
Make one stitch back into hexagon 2 (your last stitch before this one was into hexagon 3), into the chain in the corner. Then continue by joining hexagon 3 to hexagon 1.
If you are confused about this extra step, check out my video tutorial, you can see better how I did it there.
And this is how you join crochet hexagons, granny squares, and other crochet pieces with the invisible seam.
