Let’s Talk Granny Squares

I wanted this chunky granny square blanket to have a soft, squishy, almost bubble-like texture, rather than the usual open, lacy feel of traditional granny squares.

To get that look, I swapped out the usual double crochet stitches for half double crochet, which gives the fabric a denser, more plush feel. Instead of adding ch-1 spaces between my dc clusters, I skipped them entirely, keeping everything snug and cozy.

At the corners, I only used one chain instead of the usual two, which helped maintain a tight weave while still allowing the blanket to lay flat. The result? A cloud-like, ultra-soft crochet blanket with a modern twist!

This blanket can start with a magic circle but I use the chain 4 method (don’t worry, I walk you through it in the video tutorial) and is worked in rounds using granny clusters but does not use ch-1 spaces between the clusters. You’ll be building your square by working into the next corner space.

Each round is built on the one before it, so you’ll see your chunky granny squares grow with each repeat round. The corners are formed with ch-1 spaces – not the usual ch-2 spaces, giving the blanket that classic granny square look.

Want to add some colour? Just switch to the next color whenever you feel like it!

Finished Measurements

This cozy throw is made by joining 20 granny squares, each measuring 12″ x 12″, into a 4 x 5 layout. 

Once joined, the blanket measures approximately 48″ x 60” not including edging.

Colour Changes and Yarn Ends.

When changing colours at the end of each round, you can easily crochet over the tails to keep things neat and avoid extra ends to weave in later. Here’s how you can do it:

1. Colour changes are made at the end of each round by completing the slip stitch with the new colour.  Secure the ends with a knot before moving onto step 2.
2. As you start the next round, crochet over both the old and new yarn tails while making the first hdc cluster. Then, gently pull the tails to tighten them.
3. Once the first cluster is complete, tie the tails in a tight knot, making sure it stays hidden under the stitches.
4. Trim the excess, leaving one tail slightly longer to help identify the right and wrong sides of your blanket.
5. Continue the round as usual—this keeps the colour change neat with no extra weaving in later!

This method ensures your blanket stays neat and your colour changes are hidden underneath the crochet fabric.

Layout

• Arrange your squares in 4 columns across and 5 rows down to achieve the 48″ x 60″ dimensions.

• Play around with the arrangement if using different colours or patterns before joining.

Joining the Squares

You can use slip stitch join, single crochet join, or whip stitch join. Below are instructions for joining using slip stitches – this is the method I used:

Notes: Since we’re using a large hook, make sure to catch all three loops of the hdc. If you miss any, the back side of the blanket might look messy due to the looseness of the loops.

1. Lay out your squares with their right sides together.
2. Slip stitch across each row: Insert your hook through all three loops of the stitches and spaces on the edge of two squares and slip stitch across. Continue until all squares in a row are joined.  Note that you will be working through 2 hdc and 1 space.
3. Join the columns: Once all rows are joined, work in the same manner to join the columns.
4. Weave in ends to secure your work.

Finishing Border

Place a slip knot on your hook and join the yarn to any corner space of the blanket using the same colour you used to join the granny squares. Then, chain 3.

Rnd 1:  Skip 1st 2 sts, *sc in space between clusters, ch 3, skip 2 hdc* repeat from * to* around.  End with a sc in corner stitch, sl st in 1st st of starting chain and TURN. 

Continue with bobble stitch round below.

The cute little pom pom look border is made using bobble stitch (bo):

Here is how to make the Bobble Stitch (bo) for this border:

1. Ch 3, Yarn over, insert hook into the 1st ch made, yarn over and pull up a loop. (you now have 3 loops on your hook).
2. Yarn over and pull through two loops (you now have 2 loops on your hook).
3. Yarn over, insert hook into the 1st ch made, yarn over and pull up a loop. (you now have 4 loops on your hook).
4. Yarn over and pull through two loops (you now have 3 loops on your hook).
5. Repeat steps 3-4, two more times (you now have 4 then 5 loops on your hook).
6. Yarn over and pull through all 5 loops to complete the stitch.
7. Slip stitch in chain 3 space to secure the bobble stitch in place.

Rnd 2 (Bobble Stitch Round): Join to ch 3 space with a slst. *Bo, join to next ch 3 space with sl st.*  Repeat from * to * in each ch 3 space around. 

End by joining to the same spot where you first attached the yarn.  Fasten off and weave in ends.

Your 48″ x 60″ throw is now complete! 🎉 Enjoy your handmade blanket.
