Why You'll Love This Granny Square Baby Blanket with shell boarder Pattern
I absolutely love this pattern because it combines the timeless charm of the granny square with a delicate shell border that really elevates the finished piece. I enjoy how quickly the centre square grows — it is very satisfying to see the blanket take shape. The palette I used (paper white, dusty rose, candyfloss pink) gives a soft, modern look that is perfect for babies and nurseries. I also love that this pattern is beginner-friendly, so I can share it confidently with new crocheters who want a rewarding, beautiful result.
Switch Things Up
I love how easily this pattern adapts to different colourways; I often swap the dusty rose for a soft mint or pale blue for a fresh look.
To make a larger blanket, I simply add more rounds to the repeat pattern, keeping the corner increases consistent so the shape stays square.
If you want a smaller version, I use a lighter weight yarn and a smaller hook to create a mini blanket or stroller blanket.
I sometimes change the shell border to a picot edge for a more delicate finish — it gives a different vintage feel.
Try using three different neutrals for a modern, gender-neutral blanket that matches any nursery decor.
I like to embroider a tiny heart or initials on one corner for a personalized gift touch.
Swap the final pink round for a contrasting dark colour to make the shell border pop and frame the blanket visually.
I also experiment with textured stitches between granny rounds, like a round of half double crochet, to add a little density to the fabric.
For a holiday-themed blanket, pick seasonal colours and consider adding a sparkly or metallic yarn for one accent round.
When making multiple blankets, I mix and match the order of the stripes to create coordinated sets without repeating the exact same sequence each time.
Common Mistakes & How to Fix Them
✗ Skipping the initial slip stitch into the starting chain can lead to a twisted centre; always ss into the 3rd chain to join the round as instructed.
✗ Not counting clusters at the end of the round may make your corners uneven; check that you have four corner clusters after Round 1 before continuing.
✗ Changing yarn without securing tails can cause loose joins later; fasten off neatly and weave in ends before working the next colour.
✗ Working the shell border too tightly will distort the edging shape; keep a relaxed tension and practice a v-stitch in scrap before starting the border.
