Granny squares are among the most beloved motifs in the world of crochet—colorful, versatile, and timeless. But once you’ve made dozens of beautiful squares, the next step can feel intimidating: how do you join them together?

This tutorial walks you through the process of joining granny squares using the slip stitch join-as-you-go method, demonstrated with classic red, gray, and white three-round squares. This method creates a clean, flat seam that looks polished from both sides and is perfect for blankets, bags, garments, and more.

🧵 What You’ll Need:

• Contrasting or matching joining yarn (shown: red)
• Crochet hook (same size used to create your squares, typically 4.0mm–5.0mm)
• Scissors
• Yarn needle

🔗 Step-by-Step: Join-As-You-Go Method (Slip Stitch Join)

✨ Step 1: Prepare Your Squares

Lay your squares flat, with the right sides facing up. Decide in which order they will be joined.

🔁 Step 2: Begin Border on First Square

1. Attach your joining yarn (red) into a corner space of your first square.
2. Work a typical granny corner: 3 double crochets (dc), chain 2, 3 dc.
3. Continue along the edge with 3 dc clusters into chain spaces, forming one side of the square.

🔗 Step 3: Join the Second Square

1. At the corner space of your second square, attach yarn and begin the new round as usual: 3 dc, chain 1.
2. Now slip stitch into the corner chain space of the already completed square.
3. Chain 1 again, and complete the corner: 3 dc.

This connects both squares at the corner neatly.

➰ Step 4: Continue Joining Along the Side

1. Between each 3 dc cluster, work a chain 1.
2. Slip stitch into the corresponding space on the adjacent square instead of chaining alone.
3. Continue this pattern until the entire edge is joined.

💡 Tips for Best Results

• Always match stitch counts between squares to ensure alignment.
• If your squares are not perfectly even, block them before joining.
• Use a contrasting color (as shown with red) for a decorative seam.
• Keep your slip stitches loose but even to prevent puckering.
