Iris Granny Square Join As You Go Tutorial
Last Updated on January 3, 2026
This is one of the best crochet square joining methods, in my opinion! The Granny Square Join As You Go (JAYGO) method is hassle-free, taking the stress out of the joining task at the end of making a granny square blanket.
This is an easy join as you go tutorial for my Iris Granny Square pattern. It can be used to make a big granny square blanket, a quick and easy crochet baby blanket, and much more (see ideas below!).

I don’t like joining squares together in crochet, it’s one of my least favorite things in crochet. I would do that if it’s really necessary, but I will usually try to avoid it if I can. I used the Iris square pattern to make a big Granny Square blanket (Instead of working the classic Granny Square stitch, we are working the Iris stitch, which is a double V stitch).
And thought to myself that it would be so pretty as a “classic” Granny Square blanket with small crochet squares joined together.
And that’s when it hit me, that I can use the same method for the classic join as you go granny square in my Iris square! Honestly, it’s the joining method I didn’t know I needed. It spares me the joining at the end of the project, I can easily join the next square in the last round.

Join As You Go Crochet Method for the Iris Granny Squares
Joining 2 Squares Together
- Make 1 Iris Granny Square as instructed in this post. Work the square as big as you’d like, make sure to finish with round 6.
- Make a second Iris Granny Square, don’t work the last round 6.
Work the last Round 6 as follows (working only 2 sides of the square first):
Round 6: Ss in the next st and into the ch-3 sp (corner), ch 3 (counts as 1dc),
[1 dc, ch 1, 2 dc, ch 1-PM, 1 D-V] in ch-3 sp, (1 D-V in next ch-1 sp) repeat (…) until ch-3 sp (corner).
[1 D-V, ch 1-PM, 1 D-V] in next ch-3 sp (corner), (1 D-V in next ch-1 sp) repeat (…) until
ch-3 sp (corner) (pic 1). - Now that you have worked 2 sides of the square, we will start joining the 2 squares.
On the third side that we are joining, instead of working chain 1, we will slip stitch into the other square’s parallel ch-1 spaces.
In the next ch-3 sp corner: 1 D-V (pic 2), ss into marked ch-1 corner of the first square (pics2-4), 2 dc in same ch-3 sp (pic 5), ss in next parallel ch-1 sp of first square (pics 6-7), 2 dc in same ch-3 sp (pic 8).
4. Continue working the third side of the square: Work 1 D-V into each ch-1 sp – but instead of making ch-1 sp after the first 2 dc of the D-V stitch, work a ss into the parallel ch-1 sp of the second square.
Continue until you reach the ch-3 corner.
5. Now that we have reached the ch-3 corner, work this corner as follows:
In the next ch-3 sp corner: 2 dc in ch-3 sp (pic 1), ss in next parallel ch-1 sp of first square, 2 dc in same ch-3 sp (pic 2), ss into marked ch-1 corner of the first square, 1 D-V in same ch-3 sp (no ss here – pic 3).
6. Continue to finish the fourth side of the square:
* 1D-V in each ch-1 sp; Repeat from * until ch-3 (corner). Ss to top of ch-3, fasten off.
Joining 1 Square into a Corner
- Crochet the Iris Granny Square you want to join, don’t work the last round 6.
Work the last Round 6 as follows (working only 1 side of the square first):
Round 6: Ss in the next st and into the ch-3 sp (corner), ch 3 (counts as 1dc),
[1 dc, ch 1, 2 dc, ch 1-PM, 1 D-V] in ch-3 sp, (1 D-V in next ch-1 sp) repeat (…) until ch-3 sp (corner).
1 D-V in next ch-3 sp (corner), work only 1 D-V in the corner (pic 1). - Now that you have worked 1 side of the square, we will start joining the squares together.
Continue working the corner: Ss into the parallel ch-1 corner of the first square you are joining (pics 2-3), 2 dc in same ch-3 sp, ss in next parallel ch-1 sp of first square, 2 dc in same ch-3 sp. - Continue working the second side of the square: Work 1 D-V into each ch-1 sp – but instead of making ch-1 sp after the first 2 dc of the D-V stitch, work a ss into the parallel ch-1 sp of the second square.
Continue until you reach the ch-3 corner. - Working the next corner: Work 1 D-V in the ch-3 sp corner (the ss will be in the last ch-1 sp before the joined ch-1 corner – pic 4).
Ss into the joined ch-1 sp corner (pic 5), 1 D-V in the same ch-3 sp corner (the ss will be in the first ch-1 sp of the second square, after the joined ch-1 corner).
5. Continue working the third side of the square: Work 1 D-V into each ch-1 sp – but instead of making ch-1 sp after the first 2 dc of the D-V stitch, work a ss into the parallel ch-1 sp of the second square. Continue until you reach the ch-3 corner.
6. Now that we have reached the ch-3 corner, work this corner as follows:
In the next ch-3 sp corner: 2 dc in ch-3 sp, ss in next parallel ch-1 sp of second square, 2 dc in same ch-3 sp, ss into marked ch-1 corner of the second square, 1 D-V in same ch-3 sp (no ss here).
7. Continue to finish the fourth side of the square:
