Selecting the Right Yarn for Your Rainbow Blanket
When it comes to picking the yarn for a rainbow blanket, there are a few things to keep in mind. You’ll want to choose a soft and durable yarn that is easy to work with and holds up well over time. Acrylic yarn is a popular choice for crochet projects, as it is affordable, easy to care for, and comes in a wide range of colors.
For a rainbow blanket, you’ll want to pick various bright and bold colors that complement each other. I decided to use a rainbow-colored yarn called Retro Stripes from Red Heart Super Saver because it has all the bright colors in one skein of yarn without any weaving in of ends due to color changes. I also used a Lion Brand Pound of Love in White to compliment the bright colors too!
If you decide to use a different yarn that I did, then think about the color wheel. Choose colors that are opposite each other for maximum contrast, such as red and green, blue and orange, or yellow and purple when picking colors.
Other Materials Needed
To make this blanket, you will need a crochet hook, stitch markers (optional), measuring tape and a pair of scissors.
Crochet Hook
You will want to make sure to use the crochet hook size that works for you to meet the gauge. For this blanket, I used a 5 mm H hook, even though the label of the super saver yarn recommended a 5.5 mm.
5 mm (H-8)

You may also use stitch markers, which can help keep your stitch count and mark your place throughout the pattern. I also recommended having a nice pair of yarn scissors such as stork scissors on hand plus paper measuring tape, so you know you are making the correct size blanket.
Tip: If you don’t have stitch markers, you could also use a piece of scrap yarn to mark your place instead.

To make this blanket, you will need to know a few basic crochet stitches, such as the chain stitch and the double crochet stitch.
