Ready to turn your Circle to Square Granny Squares into a beautiful, cozy blanket? In this post, I’ll walk you through exactly how to join your squares, lay out your color scheme, and add a simple border to finish it off.

Whether you’re following along from my original Circle to Square Granny Square pattern or just love a good modular crochet project, this guide will help you confidently put your blanket together—and make it look polished and cohesive.

Before You Begin Joining

Joining granny squares can feel intimidating at first, but once you get in the groove, it’s surprisingly relaxing and satisfying. Before you start, make sure all your squares are the same size—blocking is your best friend here! Lay them out on a flat surface, and play around with color placement until you’re happy. You might be surprised how much shifting just one square can change the whole vibe of your blanket!

Ways To Customize Your Blanket

This pattern is super versatile! You could turn your squares into:

• A baby blanket using soft pastels
• A stash-busting scarf or wrap
• A pillow cover with just 6-9 squares
• A wall hanging using twine and tassels
• A full queen-sized blanket—just double the squares!

Mix and match solids, stripes, or textured yarns to make it your own.

Materials

• Big Twist Value Yarn (5 skeins in White, and 1 skein in each of the remaining colors: Gold, Teal, Soft Gray, Blush Pink, and Medium Rose)
• Size 5.0mm crochet hook
• Scissors
• Yarn needle

Finished Size

• About 36 inches wide by 66 inches tall
• Want a larger or smaller throw? Just crochet more or less squares!

How Many Squares Do You Need?

Each square measures 5.5″ x 5.5″ after blocking.
For a lap-sized throw (like mine), make 60 squares.

Don’t skip blocking! It helps everything line up and gives your blanket a clean, and more polished look. I like to pin my squares to shape on blocking boards and give them a gentle steam!

Layout and Color Planning

Here’s the color grid I used for my blanket layout. But feel free to get creative with your own arrangement and color combinations!

How to Join Your Granny Squares

Joining method used: Single crochet join with the seam showing on the front side. This creates a really pretty grid look to the blanket and adds a bit of an unexpected texture and character to it!

If having the seam on the front isn’t your jam, go ahead and swap it for your preferred joining method, or simply slip stitch the squares together instead and make sure your slip stitching on the back of your work.

Joining Instructions

• Step 1: Place two squares with the wrong (back) sides together, lining up your stitches.
• Step 2: Single crochet the squares together (going through all loops).
• Step 3: Continue joining in squares as you go down the row. Cut yarn. Continue adding in new rows down the line.
• Step 4: Once all rows are finished, rotate your blanket and join all the columns in the same fashion. Cut yarn.

Blanket Border

After joining, we’ll add a simple hdc border to frame the blanket and clean up our edges.

Round 1: Starting in any corner, ch 2 (ch 2 does not count as a stitch), make 5 hdc, hdc in each stitch around the blanket, making 5 hdc’s in each of the remaining corners, join with the 1st stitch of the round using slip stitch.

Round 2: ch 2 (does not count as a stitch), hdc in each stitch around the blanket, making 3 hdc’s in each center corner stitch.  Join with the first stitch of the round using slip stitch.

Cut yarn, and weave in all ends.

Enjoy!
