Colour changing yarn

Colour changing yarn is very popular for bringing that extra splash of colour to your project. Colour changing yarn is available in a multitude of weights, characteristics, qualities, fibres, and colour combinations. In our shop you will find cotton as well as wool, blends, acrylics, polyamide, nylon, bamboo and polyester - all with beautiful colour changes. We are confident that our range of colour changing yarn will cater to any taste and any crocheting or knitting project.

The many characteristics of colour changing yarn

The wonderful thing about colour changing yarn, is that you are guaranteed to get a colour variegated result, that is bound to spice up any project. All you need to do is decide which one is best suited for whatever you fancy knitting or crocheting. Naturally, it is a matter of personal taste, if you like synthetic yarn or not, but luckily (as mentioned before) we offer a wide range of colour changing yarns to choose from. This also means that we offer different yarns with both long and short colour changes, that will each bring a unique and amazing look to your project.

Good for everyday use

Try using a colour changing yarn made of 100% cotton for adding a splash of colour and pattern to your dishcloths, amigurumi, garments, hot mitts, and the like. Or make lovely shawls, hats, gloves and tops with colour changing yarn made from wool or acrylic fibre. Naturally, the colour changing yarn can also be used for making stunning afghans and toasty socks in delicious variegated shades. Making socks out of colour changing yarns have particularly gained popularity, because it really gives you the opportunity to put your own mark on the socks. This way, colour changing yarn can be used for a multitude of projects - only limited by your own imagination.

What our customers say about Colour changing yarn


Gorgeous! very light in weight and touch! I ordered 4 different colours and I was surprised to discover they are EXACTLY like shown on the pictures! One more beautiful than another. The grading is long and gentle but still noticeable, adding nice edge to my creations! The yarn is also 'flexible' what gives my hats that 'enveloping' quality. I'm definitely going to order more!


It is one of my favourite yarns for hat making! It's quite dense and the colours are great! So vivid! They never disappoint me! The change of colour happens gradually in smooth grading. Perfect for 3 mm (even 3.5mm) crochet hooks. Sometimes it gets slightly thicker when the new colour is starting, but it really is a minor difference, not affecting my knitting at all.


Really easy to work with, lovely soft cotton and the colour transitions are lovely. I would just pass on a hint though. Particularly if you start from the middle to get that version of the transition once you get about 2/3rds of the way through the yarn does come out in lumps and knot. I am now on shawl number 4 and wound the cotton off into a ball first :-)

Ellie Hooper

I am delighted with this yarn and the colours blend beautifully. Twirls Deluxe is very forgiving to work with and colour is true to images mates on website. I was very impressed with after sales service and regular updates on my order. Certainly Hobbii benefits r commendation to my crafty colleagues. I will be ordering again!


Not only was the service excellent the yarn is a delight to use. It is the first time I have used cotton king but I will be using it again! The colours are beautiful with the changes appearing in your work so subtly that you don't even realise it. An excellent product, highly recommended from an excellent company.

Linda Smith

I purchased Colour Bomb Purple Rain. Wonderful colour mix and beautifully soft. Lovely to work with. Started my project Classical Autumn Poncho (Free pattern download) the day it arrived and looking forward to seeing finished article. Delivery time was brilliant and communication great. Will deffinitely use again.

Tracy Bull

Wonderful! I bought some of this Dream Colour wool in my first order from Hobbii. It is so soft, the colours are beautiful - and I can't wait to knit with it. I will definitely order again - and buy some more of this wonderful product in another colour.

Sue Davenport

This yarn is just perfection. I ordered 2 balls of Wild Berry as it screamed “Sam” (my daughter-in-law) at me. It has done a huge scarf and a pair of fingerless mitts and I still have a ball left! Fantastic value and simply glorious quality.

Marcella McDonnell

I would love to knit mayfair because the colours are so beautiful. I'm a pensioner so I depend on people to donate wool to me. I knit for charity as I've nobody to knit for. I bought your knitting bag and I love it. It's beside me all the time.


I purchased this as I absolutely fell in love with the colour way Fairytale Rainbow. It’s is happily on its way to making the most beautiful Sophie’s Universe and looks stunning. Won’t hesitate to purchase again for another big project.
