How to join granny squares with invisible slip stitches

Learn how to join granny squares with the invisible slip stitch join, known for seamlessly melding squares together, leaving no noticeable join lines. This technique serves as an alternative to the visible slip stitch join, which creates a textured ribbing. Scroll down for a photo and video tutorial.

Tips before we begin joining squares..

1. Choose a yarn color that matches at least one of the squares.
2. Make sure that the stitches of both squares are aligned. If you are working with squares that have different stitch counts, it is helpful to use pins or stitch markers to keep the squares together nice and even.
3. Use a loose tension while joining the squares. If you tend to crochet tightly, consider using a larger hook size.

For this tutorial I’ve used the Tulip Square with worsted weight yarn and hook size 6mm.

Step 1:
Lay out your granny squares in the desired arrangement.

Step 2:
Hold two squares together with the wrong sides facing outwards.

Step 3:
Start in the corner chain of both squares. Insert your hook into the front loop of the chain facing you and the back loop of the other square. Yarn over and pull the yarn through, creating a slip stitch.

Step 4:
In the next stitch, insert your hook into the front loop of the square facing you and the back loop of the other square. Yarn over, pull the yarn through, creating a slip stitch.

Step 5:
Continue slip stitching across the sides of the squares, working through the corresponding stitches or spaces.

Step 6:
When reaching the next corner, make sure to work through the corner chains or stitches of both squares to maintain alignment.

Repeat this process for each side of the squares until all sides are joined.

Fasten off and weave in the ends.
