What I Love About This Granny Square
I’ve always loved making granny squares, and this sunburst design is definitely one of my favourites. Not only is it visually striking, but it’s also a fantastic project for beginner crocheters looking to gain confidence working in the round.
With its mix of puff and cluster stitches, the sunburst square is a touch more intricate than a traditional granny square - but don’t worry! The stitches are simple to learn, and once you get the hang of them, you’ll be making these in no time.
One Colour, Big Impact
While this granny square is traditionally made with a colour change in each round, it is less common to see it worked in one solid colour. Both styles are equally beautiful, but there is something about the solid colour that gives the design a soft, modern vintage look that feels fresh yet timeless.
Make a Blanket with Your Granny Squares!
If you’d like to transform your sunburst granny squares into a gorgeous vintage-inspired blanket, be sure to check out my step-by-step tutorial for The Oatmilk Petals Blanket. This stunning heirloom design is one that's sure to be treasured for years to come!
While I chose to make a pram/stroller-sized baby blanket with this free pattern, I’ve also instructions for twelve additional sizes ranging from lovey all the way up to king. You'll find a handy chart with all the details for each size, plus guidance on how to customise the blanket to any size you want.

Sunburst Granny Square Pattern
Start with a magic ring: watch my video tutorial here
Rnd 1: ch 2 (counts as the first dc), work 15 more dc into magic ring - refer to Photo 1.1. Pull the ring closed. Join round with a slst into top of the first dc (not the ch-2) - refer to Photos 1.2 and 1.3. (16 sts)
Rnd 2: ch 1 (doesn’t count as a stitch), ps in the same st as you joined the last round - refer to Photo 1.4 - and then in each st around. Join with a slst into the first ch-1 sp - refer to Photos 1.5 and 1.6. (16 ps and 16 ch-1 sps)
Rnd 3: ch 2 (doesn’t count as a stitch). Work a CL in same sp - refer to Photo 1.7 - then, ch 1. Note: You should have 2 chains in total – one to secure the cluster stitch, and another one after it. Continue around, working a CL in each ch-1 sp around, followed by ch 1. Join with a slst into first ch-2 sp - refer to Photos 1.8 and 1.9. (16 CL and 16 ch-2 sps)
Rnd 4: Ch 3 (counts as first tr), then in same ch-2 sp work: [2 tr, ch 2, 3 tr] - this forms the first corner - refer to Photo 1.10. In next sp work: *3 dc, then 3 hdc in next sp, then 3 dc in next sp. Into next sp work: [3 tr, ch 2, 3 tr]*. Repeat *-* 2 more times. In next sp work: 3 dc, then 3 hdc in next sp, then 3 dc in next sp. Refer to photos 1.11 and 1.12.
Instead of joining the Rnd with a slst, I like to finish with an invisible fasten off for a seamless look to the top of my square – follow the instructions below.
Invisible Fasten off Tutorial
Instead of joining your round with a slip stitch into the starting chain, try using the invisible fasten off method. It creates a seamless, polished finish for your crochet piece. Follow the steps below:
Step 1: Snip your yarn tail, leaving a 15cm tail and pull the yarn through the stitch.
Step 2: Thread yarn onto tapestry needle and find the top of the first tr st of the round (not beg ch-3). We’re going to go under the top two loops from front to back with the needle.
Step 3: Next, we’ll go back down through the centre of the last double crochet (into the same space the yarn tail is coming out of).You’ll now have a long stitch separating the first treble and final double crochet (this long stitch will sit atop of the Ch 3 that begun the round and will make a nice top for it to make it blend in with the rest of the stitches.)
Step 4: Step 4: Gently tug the tail to pull the stitch tighter just until it blends with the rest of the stitches, then flip your work and weave it through.
