Learn to Crochet the Flat Braid Join

The Flat Braid Join crochet joining method is a magical thing of crochet wonderment. I learned how to do it from my crochet idol: Priscilla Hewitt, pattern designer of such famous works as the Sunburst Granny Square (Ravelry) and the Circle of Friends Square (Ravelry), which I slightly adapted to create the Textured Circles blanket. (Free pattern)

How I learned Flat Braid Join

The pattern that I used to learn flat braid join is called Lacy Lapghan (PDF), from Priscila’s website. Now I use some type of variation of FBJ for almost all of my projects. See every project I’ve used FBJ on HERE!

FBJ Tutorial

This joining method is a join as you go, which means on the final round of the square, join it to the adjacent sides of the previously completed motifs.

First Motif

Rnd 1: (3 sc in the corner, then sc in all sts across to next corner) 4 times, slip st in first st.

Rnd 2: SC in the joining stitch, and then ch4. Skip 1 stitch and SC in the next stitch. *Ch2, skip 1 stitch, SC in next stitch* Repeat across to next corner, and (sc, ch 4, sk 1, sc) just as before to make corner. Work remaining sides to beginning, slip st in first st. Complete the first motif in this manner, and then all subsequent motifs will be joined on Rnd 2.

Remaining Square Motifs

Rnd 1: Take your next square and work the first side only up to 2 chains of the second ch4 corner. (One side will be completed only.) – See photo below.

Lay first and second motifs side by side as seen in the photo below. Drop the loop from your hook and insert the hook into the ch4 corner from front to back. Pull the loop through and complete the other 2 chains of the ch4 corner. In the photo below, I have dropped the loop, inserted the hook, and grabbed the loop. I am ready to pull the loop through and continue chaining.

[Related: I later developed this maneuver into the PLT Join! I’m almost nearly close to being famous for it]

After those 2 chains are completed, make an SC the same as in that last stitch of the corner (That is where I stopped in the photo below). Ch1, drop loop, insert hook into the CORRESPONDING ch2 space on the completed motif, and then pull the loop up through. Work a chain to complete the ch2 space, skip a stitch, and then SC in the next stitch.

To be clear: normally, you have a chain 2 space on the sides. On the sides that are joined to an adjacent motif, interrupt the chain 2 space to drop loop, pull loop through opposing chain 2 space, and complete the chain. As seen in the photo below, there is a little “twist” where two chain 2 spaces are joined. This twist (that resembles a whip stitch in a way) is made when you complete your chain after you have pulled the loop up through.

Work in this manner until the two squares are joined, and you get to the next corner.

Let’s talk about the corners

You have two corner meeting situations. Either two corners meet around the perimeter of your blanket, or they meet in the body of the blanket. Remain aware which type of corner meeting you approach, then ask yourself: Will this corner be around the edge of my blanket? Or am I working in the center? Around the perimeter of your blanket, join those corners immediately.

The spot where four corners meet in the body of your blanket, is worked in a special way, in order to create perfectly crossing corners.

Here is what I do with the corners

When you come to a corner that you know is in the center of your blanket, LEAVE IT ALONE. See photo below. These two corners will soon be picked up by their diagonal partners, so for now, they are just hanging out.

Okay, in the photo below, I have a diagonal corner pairing and I have a corner loop that has not yet been picked up – you can see that the bottom square is not yet joined. One diagonal pair crosses over the other one. Make all crosses facing the same direction, instead of accidentally crossing the other way, because it is super-noticeable.

Below, three different corner meeting situations occur

  1. At the top left, four corners joined up.
  2. Top right, a loop waits to be picked up by the diagonal square, and
  3. Bottom left, both loops await their diagonal partners.

Remember, When you get to the final row of squares, join adjacent corners immediately, as this will be around the perimeter.


Optional Border

Once you finish joining, you can work a reverse SC round. I work 2 reverse SC stitches in each chain 2 space. I skip over the SCs because the reverse SC is naturally large… many times, I will go down a hook size so that the border is not stretched out. Here, I stay with the same hook size.

  1. Hello,
    Thank you for all the work you’ve put into this, so we can benefit from it.
    However, the last thing you say about the perimeter is that you do a “back SC in each ch2 space”. What on earth is a
    “back SC”? I’ve been crocheting for many years, but never heard about this.
    Could you explain it, and maybe show what you mean?
    Thank you again,

    • Hi there! This is “reverse SC” or “Crab Stitch” you can google / search those terms and find YouTube videos that will help much more than me! 🙂 Happy Crafting to you! 🙂 ❤️❤️

  2. Thanks for this tutorial I knew how to do the flat braid but always had problems with the center klinjngs. Your explanation and pics helped immensely.

  3. Any chance of getting this tutorial as a pdf to save on my computer, please?
    Please would you email this to me?

    • Me too! I’m just not ready for videos yet.. But there’s plenty of them out there!

      And I’ll get there. I take my time planning and I don’t move forward on something until I think I’ll do a good job on it. 🙂 So it’s on my to do list!
      Happy crafting!

  4. This is what I have been looking for! My only problem is that I need to join hexigons! Do you think this method would work with a three-way join, leaving two loops free at the corners and connecting all three when doing the last corner?

  5. Hello and thanks for the instructions, very detailed. The pattern i have calls for six columns and nine rows, your example does four squares join together, what do I do to get the six columns?

    • You would just keep joining making sure you pay attention to which squares are on the outside of your blanket. How you work the corners is determined by whether the corner is in the “center” of the blanket, or around the outside. So as long as you pay attention to that, you can make as many rows or columns as you need. Hope this helps! — Rachele C.

  6. Hi Rachele,
    I am a big fan of your work!
    I am making a square and the last row is a HDC – would that work for this join or would I have to SC around for the last row?

  7. Thanks for this great tutorial! My blanket would be a mess without them.

    Question. I’m making a blanket with multiple 12″ squares, and one large 26″ square. I would like the smaller squares to surround the larger square. How do you suggest I stitch the part where two corners of the smaller squares come together with the straight side of the large square?

    I can post pictures if this doesn’t make sense!

    • Mhm I know what you mean – so what I always do is work the 2 smaller squares corners into 1 spot if that makes sense… that way nothing is left hanging, and there’s not a gap between. You may have to do some fancy footwork on the number of chain spaces that you make, but just work your loops around the large square first, then work loops around the smaller squares, joining them on the side, and be sure 2 small square corners meet in 1 loop on the large square. – Any time you’d like to send pics to, id love to see ❤️
