What I Love About This Sunburst Granny Square
I really enjoy working up a granny square and the Sunburst Granny Square is one of my favourites. With its radiating rounds of puff and cluster stitches, it creates a beautiful texture and a soft, floral-like appearance. Whether you're making a blanket, cushion, bag, garment, or wall hanging, this square is a versatile building block. And with the option to change colours in each round, the design possibilities are endless.

Let's Talk Yarn!
I wanted to create a delicate, summer-weight blanket for the warmer months, so I chose a lightweight linen-cotton blend yarn to give the Oatmilk Petals Blanket a soft, airy feel.
Specifically, I used Hobbii Rococo Linen in the shade Lace - a gorgeous blend of 34% cotton, 30% linen, and 36% viscose. This yarn is lovely to work with and has a subtle, natural texture thanks to the way the fibres are spun together. I was pleasantly surprised by how soft it felt - especially compared to some of the scratchier linen blends I've used in the past. It has a beautiful drape that adds elegance to the finished fabric, and its neutral cream and oat tones perfectly captured the vintage-inspired aesthetic I was aiming for.
You can use any yarn weight for this pattern - just keep in mind that it will affect the final size, drape, and overall feel of your blanket. I’d love to make a cozy winter version using a heathered worsted weight yarn!

Blanket Sizing
While I decided to crochet a pram/stroller baby blanket with this free pattern, I’ve also included twelve other sizes ranging from lovey to king. This way, whether you're wanting a cozy throw or a large bedspread, you'll find the perfect size to suit your needs.
Below, you'll find a handy chart that lists each blanket size along with the information you'll need to create your own Oatmilk Petals Blanket in the size that's just right for you. Whether it's a gift or for your own home, this pattern adapts beautifully to a wide range of sizes.

The Oatmilk Petals Blanket Pattern
Sunburst Granny Square
For the Oatmilk Petals baby blanket you will need to crochet 80 squares of the Sunburst Granny Square. Click HERE to be taken to the step-by-step photo tutorial OR watch the video tutorial below.
Joining Your Sunburst Granny Squares
Once you have all 80 squares, it' time to join them together.
For this blanket, I used my favourite method of joining squares...the flat slip stitch seam. This method produces lines that are flat but clearly defined, framing the squares beautifully.

You can absolutely use your preferred method of joining if you have one - or click HERE to be taken to the step-by-step photo tutorial for the flat slip stitch seam OR watch the video tutorial below.
Blanket Border
You will now finish your blanket off with a border consisting of 6 simple rounds.
Note: I will continue using the 4 square sample from the slip stitch seam tutorial, with white yarn to join so the stitches can be seen clearly.
Join yarn with a slst into any corner ch-2 sp and ch 1 - refer to Photo 1.1:

Rnd 1: work 3 sc into ch-2 sp, continue working evenly around the blanket, working a sc into each st and 3 sc in each corner ch-2 sp. Into each join (where 2 squares meet) work 1 sc on either side. Slst into the top of the first sc to join the round. Refer to Photo 1.2.

Rnd 2: ch 2 (counts as first hdc throughout), work 3 hdc into next st (corner st), continue around the blanket, working 1 hdc into each st around, with 3 hdc in each corner st. Slst into the top of the first ch-2 to join the round. Refer to Photo 1.3.

Rnd 3: ch 2, hdc in next st, work 3 hdc into next st (corner st), continue around the blanket, working 1 hdc into each st around, with 3 hdc in each corner st. Slst into the top of the first ch-2 to join the round.
Rnd 4: ch 2, hdc in next 2 sts, work 3 hdc into next st (corner st), continue around the blanket, working 1 hdc into each st around, with 3 hdc in each corner st. Slst into the top of the first ch-2 to join the round. Fasten off and weave in ends.
Rnd 5: Join the same yarn you used for your granny squares (or any other accent colour) with a slst into any st. Slst into each st around the entire blanket. Slst into first st to join the round. Fasten off and weave in ends. Refer to Photo 1.4.

Rnd 6: Rejoin white yarn with a slst into any st in Rnd 4. Refer to Photo 1.5.

Sc into each st around blanket, working 3 sc in each corner st. Slst into the top of the first sc to join the round. Fasten off and weave in ends. Refer to Photo 1.6.
