The sunburst granny square blanket is a beautiful and popular crochet pattern that features a circular motif with a burst of radiating colors. This style of granny square uses multiple colors and can be customized to match any color scheme. The pattern involves working clusters of stitches to create a textured, three-dimensional look. As you continue to work, the rounds expand to create a large square.

Gauge: your personal tension will determine the size of your squares and the amount of squares you will need for you desired size. The blanket pictured below used one ball of the pale rose and one ball of the duck egg, one and a half balls of wisteria and almost two full balls of cream. It’s a small baby blanket measuring 33.5 inches long and 23 inches wide including the border.  The squares measure at 4X4 inches each.

    I am really looking forward to doing the CAL, I am eagerly waiting for the 8th to start! I have just ordered my yarn in suitable colours that will blend in with my living room so that I can have the blanket on my sofa. The Sunburst blanket has been on my list to do for a while so I am so excited about it!

      Hi Rachel I’m so pleased that you are joining in with the CAL, it’s so exciting isn’t it 🙂

    What colors would you recommend in Caron Simply Soft to be more beachy or oceany (besides the seafoam colors) ? Uhm, more blue hues if I am not clear.
    Thanks for response in advance.

      Hi Laura If you want to include more ocean shades you could incorporate some of the green/teal shades such as Robin’s Egg. For a beach feel you can look at shades of coral and pinks too

    I meant to start on the CAL but completely forgot. I still want to be involved. One question I do have. I have so much wool stash here at home. Does the Sunburst Blanket have to be in the suggested wool or are we able to do it with our own stash of wool?

    • BellaCocoTeam

      Hi Chris you can do the blanket with whichever yarn you wish, just be mindful that depending on what yarn and hook size you are using your blanket maybe a different size 🙂

        Hi, Thank you for your reply. I am going to do a test granny square just to see what the finished size is and then decide what wool I am going to use. This will be my first blanket so looking forward to it.

    I completely completely missed the boat on the CAL, but I have some beautiful Paintbox lemon cream DK (250g left over from a knitting project) and a niece with a baby on the way, so I’d love to catch up to turn it into a baby blanket with cream and another colour or two (suggestions welcome!). Can I catch up on missed sessions? Are they recorded at all? And can I join the last sessions or is it too late? Sorry for so many questions, Thank you!

    I was not able t do the CAL for 2021 and it looks like all the weekly boxes you would click on are disabled. I also tried the link above that the Bella Coco Team provided in a post above but I get the same results that all the weeks are disabled. Is there a place that these things are archived? Now that I have the time I can’t access the steps.
