Hi, Welcome, thanks for stopping by, here you can get the free crochet pattern for a colourful bright rainbow granny square baby blanket…… but only using one ball of the colourful yarn!
Yep – not more going to the shop to buy a lots of balls of yarn when all the colours can be found in ONE BALL/ Skein of Yarn.
This was a great make, quick, easy, methodical and repetitive. This design uses the Continuous Join as You Go Technique for the grey – so the bonus is only TWO ends to sew in when you get to the grey!
>>>Find out about the Continuous Join As You GO technique here with a handy video.

A bit of background on the Rainbow Granny Square Blanket Design
It was pouring with rain, Home schooling was taking a break for the afternoon as we’d just found a brand new series on Prime – Alex Rider!
I asked the pink one to choose a ball of yarn for me to make granny squares with. Little mini granny squares, one round only, and see how many I could make.
I have to give credit here to how I came up with the idea, a lovely lady on Instagram, who did my NoBrainerCAL – and has the most amazing crochet feed.

Please head over and check out @Jo_Kill on Instagram. She made a similar blanket – using mini granny squares, but then made it completely different to this one by following the #spinyourgrannyblanket by @stitchedupcrafts.
The rainbow yarn:
Well this is the magic part of this whole project. Rather than use a whole load of different colours from my every growing stash, one ball that self changes – thats all I needed.
So what did the pink one choose?
Boho Spirit in Festival

Pretty Pretty…..
I’ve no idea how I even got this one (it’s one of the happy accidents to end up in my yarn stash) – but it sure is colouful.

So mini granny squares. 1 round each – and they worked up super quickly (probably because I didn’t sew my ends in as I went!)

A few hours later and I had crocheted a ball of wool into a colourful rainbow.

To keep all the squares in order, I used a length of t-shirt yarn and added them to the string as I made them.
How pretty is the rainbow snake?

Round 2 – this is where it became interesting. What colour to go around next, and not take away from the colourfulness of the bright squares?
After a bit of deliberation – white was decided. I used Cygnet DK from my stash – but any white yarn will do.

I even started to sew in the ends at this point!
A lot of squares later……..

And a few more…..

It was time to decide on an order. This took a LOT of time, and a lot of reordering!

I tried changing it so the colours went diagonally…….
But there being so many squares, the what looked lovely at the top of the right picture – blues purples, looked a bit weird in the opposite corner, green, yellow and purple……. with no blues in sight!
At this point I got a little frustrated!
I went straight back to the drawing board.

I went with a kind of snake it up – like snakes and ladders, get to the end of one row, and immediately come back the other way.

Decision made!
Then the outside of the squares for joining?

I started with a parchment colour, but it looked a bit too bland.

Dark grey didn’t look right either.
New yarn order needed……
This is an amazing yarn and well worth a look at if you want a premium acrylic baby yarn.
I used this yarn to make this blanket – and it is amazing!

So – Continuous join as you go – this has been a revolution!
You can find out all about it here – with a video tutorial too!
