Gauge & Sizing Notes
Don’t skip the gauge swatch! It’s vital for ensuring your Dolphin Blue Granny Square Blanket turns out just the way you envision. For this project, your crochet gauge should measure 4×4 inches (10×10 cm) as 5 rounds in pattern = 11 cm square. If you find your squares are too small or large, you can easily adjust your size. To make your blanket wider, simply increase your starting chain in multiples of 6. Conversely, if your swatch tension doesn’t match, and you find your work tighter than expected, try changing to a larger hook size. Happy crocheting!
Step‑by‑Step Pattern for Dolphin Blue Granny Square Blanket
Row 1: Foundation Ring
Start by making a slip knot and chaining 4 (ch4), then join with a slip stitch (sl st) to form a ring. Optionally, you can create a magic ring. This foundational step will prepare you for creating your Granny Squares, and your work should look like a small loop.
Round 1: First Round of Granny Square
Chain 3 (ch3) which counts as your first treble crochet (tr). In the ring, work 2tr, followed by (ch2, 3tr) three times, ensuring to complete the clusters. After your last cluster, ch2 and join with a sl st to the top of the initial ch3. Your round should now contain 12 tr plus corner chains (12 sts).
Round 2: Expanding the Square
Begin this round by sl st to the next ch2 space, then ch3 (counts as first tr). Work in the same ch2 space: (3tr, ch2, 3tr) to create the corner. In the next ch2 space, work (3tr) and repeat for each corner. After completing the round, join with a sl st, resulting in 24 tr plus corner chains (24 sts).
Round 3: Continuing the Growth
Slip stitch into the next ch2 space and begin with ch3. In the same space, work (3tr, ch2, 3tr) for the corner. Then, in each subsequent ch2 space, continue (3tr). Repeat the process around, joining with a sl st at the end. You’ll now have 36 tr plus corner chains (36 sts).
Round 4: Larger Squares
Slip stitch into the next ch2 space, then ch3, and work (3tr, ch2, 3tr) for the corner. This time, in each ch2 space between corners, work (3tr) twice. Join with a sl st, leading to a total of 48 tr, plus corner chains (48 sts).
Round 5: Final Round of Squares
Again, slip stitch into the next ch2 space and ch3. Create the corner with (3tr, ch2, 3tr). In the spaces between corners, work (3tr) three times. Conclude the round by joining with a sl st, giving you 60 tr, along with corner chains (60 sts).
Step 6: Joining Squares
To join, use the Dolphin Blue (G) yarn during the final round of each square. While doing the corner (3tr, ch2, 3tr) in the current square, connect to the adjacent square where indicated. This innovative join-as-you-go method binds your squares effortlessly, ensuring they blend beautifully.
Step 7: Adding the Border
For the border, attach your joining color (G) at any corner. Work 3 rounds, treating each corner with (3tr, ch2, 3tr), and in the spaces between corner clusters, work (3tr). Upon completion, your blanket will have a tidy finish that frames the colorful Granny Squares elegantly.

Expert Tips for Granny Square Success
-
Keep Tension Even: Consistent tension is key. Make sure your stitches are neither too tight nor too loose to maintain uniformity in your Dolphin Blue Granny Square Blanket.
-
Count Those Stitches: After each round, take a moment to count your stitches. This habit helps prevent distortion and ensures each square maintains its shape.
-
Mind the Edges: When joining squares, ensure your edges align properly. Use stitch markers to hold squares in place as you crochet the join-as-you-go.
-
Finish Neatly: Weave in your ends carefully. A needle helps blend the end strands into the stitches for a clean look, keeping your beautiful blanket polished.
-
Gauge Matters: While gauge isn’t critical, checking that your squares measure accurately can avoid running out of yarn and help achieve the desired final size for your blanket.

Dolphin Blue Granny Square Blanket FAQs
Can I substitute yarn for this project?
Absolutely! While the pattern calls for DK weight yarn, you can easily substitute it with other fiber types. For instance, swapping acrylic for cotton can change the texture and drape, so just keep in mind that cotton may result in a denser fabric. Make sure to check your gauge as you go to ensure your squares still turn out the right size!
How do I adjust the size of the blanket?
Don’t panic! Adjusting the size of your Dolphin Blue Granny Square Blanket is simple. To make it larger, just increase the number of Granny Squares you make; for a smaller size, reduce the number of squares. For example, if you want to make a throw size, consider using only one or two rows of squares.
What should I do if my work is curling?
If your Granny Squares are curling up like a bowl, take a moment to check your tension. This often happens if your stitches are too tight. Relax your grip on the yarn a bit and consider using a larger hook size to see if that resolves the issue. It’s an easy fix, and you’ll love the results!
What hook size should I use?
For the Dolphin Blue Granny Square Blanket, a 4mm (G-6) hook is recommended. However, if you’re not achieving the desired gauge, feel free to try a different size. Remember, your aim is to have squares that measure approximately 11cm x 11cm after five rounds!
How do I fix dropped stitches in my squares?
Don’t fret if you find a dropped stitch! To fix it, carefully pull the yarn back to the missed stitch and reinsert your hook. You can crochet that stitch back up the chain or use a needle to weave it into the fabric for a clean repair. Keeping a close eye on your stitch counts will help minimize these surprises!
How do I care for my finished blanket?
To keep your Dolphin Blue Granny Square Blanket looking its best, hand wash it or use the gentle cycle on your machine. Always dry it flat to prevent stretching. This way, your beautiful creation will maintain its shape and snuggly softness for many cozy moments to come!
