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

Terry Noble

The colors of this yarn were so pretty that I ordered the Color Bomb yarn cakes in three different colors. I am delighted with all the colors and was surprised at how soft the yarn feels. I knit and crochet shawls for a prayer shawl group and Cotton Kings will be perfect for summer shawls. At 1000 meters this yarn will make a generously-sized shawl with no need to join in the middle. I am sure that I will be ordering more!

Olivia DeBalli Miller

I love this yarn. It’s going to make beautiful doilies for my living room. It’s the perfect weight and texture. And the color is so brilliant and bright as it is pictured in the blue shade. I’m so happy I purchased more than I need for gifts because it’s soon to be discontinued. I would definitely recommend this brand for dollies and crochet projects. I worked with it and I’m REALLY pleased!

Melanie Pierce

This yarn came way quicker than expected! I have never used cotton blend or such thin yarn but I can tell it is top quality and the color transitions are working up beautifully! It is so soft and I will be using it for 2 different projects because there is quite a bit of yarn in one cake. I will definitely be ordering more products from hobbii!! I used 502 fairytale rainbow! 🌈

Evelyne Sawyer

This yarn was a joy to knit with.I wondered if I would be able to match the pr.of socks that I made. well, they came so close, that I possibly was the only one that could find a difference.These will make some person happy this Christmas and I am going to make myself a pr. as well and not even worry about matching. Either way, the blending of the yarn is fabulous.

Pat Romeo Boyle

I have been looking for rag type wool for a while and am pleased that this is available. I knit socks for my husband, who is a type 2 diabetic, and he finds the hand knit socks feel better on his feet. These will have the cushion he appreciates and they remind me of the hiking socks we would purchase over 50 years ago from LL Bean in Maine USA.


I love this mystery bag yarn! I have a new grandbaby on the way and I'm going to make some super fun wash clothes with this. The colors are beautiful and very soft. I'm excited to say that my first order from you (there was more than just this) came quickly and without incident. I'll be ordering a lot more yarn in the future. Thank you!

Kerri O’Connell

I just received my mystery bag and have already crocheted a little girls cardigan out of this beautiful quality and super soft yarn!!! The customer service from Hobbii is amazing. I live in Australia and could not believe how quickly I received my yarn. I will definitely be making more purchases soon, just love it!!!!!

Shar Schultz

This yarn is just lovely. I purchased 4 bags worth! the cotton is lovely, colours look really good and I loved the easy start labels as this has just made it that much more easier! Delivery was quick as well. I wouldn't hesitate buying this yarn or any other yarn from this company! Thank you Hobii!!

Evelyn Shore

Delighted with the speedy delivery. And the yarn is so special. The colors are beautiful. Just what I had hoped for. Concerned at first because you are a new company to me and so far away. But so pleasantly surprised. I am going to enjoy knitting with yarn this summer in Florida..

Alise Chaffins

I’ve purchased 5 cakes of 503 and I absolutely love it. It’s so easy to work with, the texture is soft and light and the color gradient is just wonderful. Fast shipping, amazing customer service, and a gorgeous product. I would absolutely recommend this yarn and this company!
