The Christmas crafting has begun. I can not tell you how in love I am with these rainbow blocks! The colours are amazing, aren’t they? And they couldn’t be easier to make. It only took one evening in front of the telly to dye 200 blocks.

I’m keeping one set of 50 blocks for Jack and Sarah and will be gifting the other three sets. They turned out so beautifully though that I am thinking of making some more.

So, you want to make some now too, don’t you?

How to Make Rainbow Blocks


  • Jumbling Towers (K-mart’s generic Jenga blocks) – I bought 4 tins (48 blocks in each) for $6 a tin. Bargain!
  • Liquid Watercolours – We have these Watercolor Magic ones. Or if you’re outside Australia, you can find them here on Amazon
  • Shallow saucer or flat-based dish – it needs to be flat otherwise the dye will run to the corners and be difficult to use
  • Cooling rack – I just used my cake cooling rack
  • Towel – to protect the table

How to make rainbow blocks - An Everyday StoryHow to make rainbow blocks - An Everyday Story Process:

  • Divide your blocks into the number of colours you’ve chosen
  • Set up your space; lay the towel, have your blocks on one side and the cooling rack on the other. You need to work quite quickly so it is good to have your space set up before you start
  • Start with the lightest colour. For me that was yellow. Pour a few drops of liquid watercolour on the saucer. You are going to get dye on your fingers and this can transfer to other blocks. I started with red (and then yellow) and so a couple of my yellow blocks have red spots from my dyed fingers. If you start with the lightest colour, you won’t notice any marks as you move through the darker colours
  • The blocks dye quickly. If you leave them in the saucer they will soak up a LOT of colour. You need to move quickly. Place one block at a time in the liquid watercolour; roll it to colour it, then quickly take it out. It only takes about 5 seconds to dye one block. Place your block on the cooling rack
  • Leave it to dry and you are done. You can seal them with spray sealant but I don’t think I will bother. If you don’t seal them, the colour will bleed if the blocks get wet. So you’ll need to make sure they stay dry.

Aren’t they gorgeous?! I can hardly wait to give them to Jack and Sarah. I know they are going to LOVE them.

The idea for the blocks came from this really fabulous new kids’ book called, 150+ Screen-Free Activities for Kids: The Very Best and Easiest Playtime Activities from!

This book is incredible. You really must take a look at it.

I’ll show you a few more activities from the book with a full review on Friday but if you are thinking about ordering it for Christmas, get in quick because it is selling out all over the place like crazy!

You can have a look on Amazon, try Adams Media Bookstore, or check your local bookstore.

There’s a bit of a rainbow theme going for my Christmas gifts this year. I have another little project on the go at the moment which I’ll show you next week.

So who else is Christmas crafting this year? And who is going to make some of these blocks?!!

  1. I tried dying blocks with food dye last year – it worked quite well, except you don’t get that awesome purple!
    I keep hoping that I’ll find a cheaper version of the liquid water colours, but maybe I’ll just have to bite the bullet and buy them (or add them to my Christmas list..)

  2. These look lovely!! I’m very inspired, thanks for sharing 🙂

  3. Ha ha! I just spent a good chunk of my Saturday dyeing some wood toys for my boys for Christmas! Balance balls, little men with hard hats, graduated hearts, cubes, and discs, balls and candle pots. My colors didn’t come out as bright as yours though. Perhaps I should get this set of watercolors! It took me a long time because I prefer the wood to be smooth, so I smoothed them all with sand-paper first! Then I hand-painted each one.

    These look wonderful! The children will love them.

    1. Oh yes, and then I sealed them with a coconut oil & beeswax polish!
      I’m excited for the boys to see them!

  4. They look gorgeous Kate!

  5. I love these so much!!!

  6. Oh those are just gorgeous! I think I just found a perfect gift idea for my children and my nephew! Thanks so much. Will have to investigate the liquid watercolours too.

  7. Gorgeous!!! What are options for sealing them besides the spray sealant? How would I seal with something like CO or beeswax?
