SUNBURST GRANNY SQUARE PATTERN

  • Round 1. Using your first colour (I used Banana Cream), create slip knot, chain 5 and then join with a slip stitch. Chain 3 (this will count as your first treble crochet) Work 15 treble crochet stitches into the centre circle. Next, insert hook into the third chain from the hook (your original chain 3) slip stitch and then fasten off. You should have 16 stitches in total (including your chain 3).
  • Round 2. Attach your next colour (I used Mint Green) into any chain space of the previous row. Chain one and work a puff stitch into that same chain space. Continue around, working a puff stitch into each treble chain space. Next, Slip stitch into first puff stitch and fasten off. As a result, you should have 16 puff stitches in total.
  • Round 3. Then, attach your next colour (I used Baby Lilac) into any chain space of the previous round. Chain 2 and work a cluster stitch into the same chain space, chain 2. Next, continue around, working a cluster stitch into each puff stitch chain space chaining 2 between each stitch. Then, slip stitch into the first cluster stitch and fasten off. As a result, you should have 16 cluster stitches in total.
  • Round 4. For this round we will be turning our circle into a square. Attach your next colour (I used Champagne White) into any chain space from the previous round.
The three first stages of the sunburst granny square sit together on a white background.

    Hi
    How many balls of yarn did you use for the sunburst granny blanket?
    Thanks

      Hi Lynne it’s really difficult to answer this question as it would depend on the yarn you use, your hook size and your tension. If you do a some squares you may then be able to work out how many balls you would need.:)

    Beautiful pattern Sarah-Jayne I can’t wait to start.
    I can’t seem to work out how many balls of yarn I need in each colour.
    Sorry if I’m missing it somewhere, but I’d love to know how much I need to buy.
    Thank you for the pattern and for generously sharing it.

      Hi Meas

      You’re very welcome, I’m so glad you like the pattern It does depend on which yarn you want to use and which hook size, but as a rule of thumb I would advise to get one ball of each colour and one or two balls of the main joining colour. You can always buy more but sometimes the dye lots differ and then you could end up with slightly different shades, so best to buy all together if possible.

      Hope this helps.

      Hi denna I used one ball of each and a 4mm hook size. However the amount of yarn you use will depend on how big you want the blanket to be and will also depend on your tension 🙂

    Hi Sarah-Jayne,

    In relation to “How many balls” used….how many did you use & how many squares did you end up with? And what size (dimensions) was your throw/blanket?

    This will give me a bit of an idea (roughly) to how much more (if any main colour like your “champaign” to get)

    Thx heaps

      Hi Chris I can’t really answer these questions for you as it would totally depend on what yarn you use, your hook size and your tension. Maybe you could make a square measure it and then work out how much yarn and how many squares you will need from there. Sorry I couldn’t be of more help. Good luck with your project and let me know how you get on:)

    Hello Sarah Jane I’m making the sunburst granny square blanket and wondering if I need to block the squares individually or the blanket as a whole unit?
    I have really enjoyed crocheting using your pattern so thank you.

      I’m really happy you liked this pattern I would recommend blocking each square individually as this will make it easier to line them up when you start joining them.

    Hi Bella Crochet,you teach very beautifully and with patience I see all your videos. At present I’m working with sunburst granny squares and happened to visit this page for increases in size or rounds from 5 to 8 ,but while doing so I notice the written instructions for round 4 are missing.
    Please check this and add it as it will help a lot of beginners like me..
    Thank you and hoping to learn a lot from you..I have voted you in UK competition.

      Hi Sangita, thank you so much for your kind words and for voting for me I’ve had a look at the instructions on my website and it appears there are some errors with the formatting, so thanks for bringing this to my attention. The instructions that are listed as rounds 5 to 8 are actually the instructions for each side of round 4. I will have this edited now

      Hi Clare this would obviously depend on how big you want the blanket to be along with the yarn you use, your hook size and your tension. Maybe you could do a few squares till you get to the width you want then work it out from their ? I wish you the best of luck 🙂

    Hi..and thanks for this lovely well written pattern. I’m just wondering if the stitches in round three are all cluster stitches or all puff stitches? Am I reading it right if I do a cluster stitch to start the round and then puff stitches all the way round till the join?? I’m finding it a little confusing but I’m entirely sure it’s me and not your pattern !

      Hi Carla You’re very welcome The stitches in round three of the pattern should all be cluster stitches – it appears you’ve picked up on a typo in the pattern so I’m really sorry that I’ve caused you confusion! I’ll have this amended asap.

    Hi thank you Sarah-Jayne for this lovely pattern.

    Just want to ask when I’m working on the corners of Round 4 where there are stitches of different height, I tend to have the corners more and more loose (like the last corner is much loosely-spaced than the first corner). I am struggling with how to manage the height of those different stitches…(how tall/loose should the golden loop or working loop be…)

    Could you offer some tips on tension and height problems when crocheting consecutive stitches that have different height? I have tried to search on youtube and google but can’t seem to be able to find proper help.

    Thank you in advance for your help!

      You’re welcome, I’m glad you like the pattern You can find some hints and tips for tension in my tutorial here: https://www.youtube.com/watch?v=SRVA_4uNsNw&t=1s but as with most things, the more you practise the better you will get and you should find that after completing a few squares, your stitches begin to look a lot more uniform. You can also try skipping the chain one in between each cluster of stitches as this can pull the stitches tighter and make them look neater.

      In any case I would try not to overthink it too much, as you should find that blocking your squares once they are finished will sort it out anyway To do this you just need to stretch and pin out the squares into shape, and for acrylic use an iron held a couple of inches above to carefully blast steam to set the stitches into shape.

      Hope this helps and good luck!

    I just love this blanket and the colors are gorgeous. I found your site from one of the Le Petit Saint Crochet videos. I’ve been knitting and crocheting for over 40 years but am finding a lot more time… actually I’m MAKING at lot more time to do it so all these beautiful patterns are giving me tons of inspiration. Thank you!

    Love your patterns and am a follower on YouTube. However, I do wish you would let us know the finished size of this and other granny squares. I’m not only looking for unique granny squares but I’m often looking for particular sizes. It would be so helpful! Thank you!

      The size often depends on personal tension along with the type of yarn used and hook size so it’s really difficult to give specific sizes 🙂

    Thanks so much for this! If I wanted to make the square bigger, i.e. add another round, how would I do that? Just using clusters of trebles like a traditional granny square? Thanks in advance for your help!

      January 17, 2022 at 9:12 pm

      Hi Donna You’re welcome! Yes, you would just need to work a round (or several rounds if you wanted) of treble clusters in exactly the same way as you would when making a traditional granny square.
