Introduction

This pattern is a variation of the classic 6-Day Kid Blanket (6DKB), worked in the drama-free Tranquility Stripe, which features the same foundational six rows of single crochet, double crochet, and double crochet granny clusters without the characteristic chevrons of the 6DKB. The dreamy Retro Rainbow colored stripes are finished off with an adorable floating clouds border – a variation of #14 from Edie Eckman’s book “Around the Corner Crochet Borders.”

There is also a baby blanket version of this pattern, the 6-Day Retro Rainbow Baby Blanket.

This image features a vibrant, handmade crochet blanket beautifully spread out in a semi-circle or fan shape, showcasing the full spectrum of its bright and colorful stripe pattern. The texture and craftsmanship of the crochet work are prominently highlighted by the way the blanket is arranged. The Crochet Pattern for this blanket is the Retro Rainbow Crochet Pattern by Betty McKnit founder of 6-Day Crochet and creator of the viral 6-Day Kid Blanket and 6-Day Star Blanket. Each row is carefully color-coordinated, creating a rainbow or neon-inspired motif. Part of the white scalloped trim is visible on one edge, giving a soft, finished look to the overall piece.

What’s the difference between this pattern and the original 6-Day Blanket?

  • Size – this pattern makes full-size blanket, the original pattern made a toddler sized blanket. This pattern can also written to be easily adaptable.
  • Yarn Weight – The original blanket used chunky weight yarn, this pattern uses worsted weight, and is adaptable to different weights of yarns.
  • Edge and Border – this pattern has instructions for an edge and a custom-designed-by-Betty (inspired by Edie) border. The original only gave instructions for tassels. 
  • Stitches: this pattern uses the same six rows of stitches as the original 6-Day Kid Blanket uses minus the chevrons.

You can make this blanket with any number of colors you like. My favorite number of colors for this stripe is seven colors and changing colors every row. I like having one more color than repeat rows, so that the colors shift rows on each repeat.

Hook: J (6.5 mm), and I (6 mm)
(make a swatch to determine the best hook for your yarn and for resizing purposes).

The Crochet Pattern for this blanket is the Retro Rainbow Crochet Pattern by Betty McKnit founder of 6-Day Crochet and creator of the viral 6-Day Kid Blanket and 6-Day Star Blanket. The outer edge is finished with a white scalloped shell stitch border, giving a delicate, lacy finish. The blanket uses a rainbow sequence of bold and bright colors. The color pattern is carefully repeated and alternated, making the design symmetrical and balanced.

Does it Really Only Take Six Days?

All of my patterns that use the same six rows alternating rows of sc, dc, and clusters, with or without chevrons, is named 6-Day Crochet. The name of this pattern comes from the original 6-Day Kid Blanket, which was toddler sized and made with chunky yarn, and took me an easy six days to make. This variation uses the same stitches as that original pattern, but you can use any yarn and make it any size you want. Whether you can meet the six day deadline will depend on several factors, including your experience and speed with which you crochet, and how much time you have to spend each day crocheting, what yarn you use, and what size blanket you wish to create. It is 100% possible to complete a large blanket in six days, regardless, you will love how fast the 6-Day Retro Rainbow Blanket works up. 

For more information please see my article, Why is it Called the 6-Day Kid Blanket?

Tips for Completing in Six Days

To complete this project in six days:

  • Plan to spend 3-4 hours per day crocheting.
  • Use worsted weight or heavier yarn.
  • Limit the size of your blanket to 163 starting chains or less.

First Timers

This is an easy pattern, and a good option for newer crocheters, but it is not meant to be a beginner pattern. I assume you already know how to chain, single crochet, and double crochet, and I don’t teach those skills in this pattern. There are plenty of resources online and elsewhere to learn those beginning crochet skills.

You will also need to be brave enough to read this whole pattern and follow instructions here. I have very good tutorials on YouTube that will help you, but they are only meant to help with this pattern, they are not a replacement for this written pattern.

How to Resize

You will need to make a swatch with your chosen yarn and hook. Start by chaining 21 and follow the stitch instructions below through Row 7, repeat Rows 2-7, and then 2-4.

Measure your swatch to determine how many chains to start with to achieve your desired width, and to determine how many repeats you will need for your desired length. The starting chain multiple is 3.

Side Edges

This pattern utilizes the stacked single crochet at the start of the rows in order to create straight side edges. Please see the abbreviations at the beginning of this pattern for an explanation of the stitch. stsc counts as 1 dc.

This image shows a colorful crocheted blanket draped over a lime-green cushioned outdoor sofa. The blanket is made up of a repeating stripe pattern using various crochet stitches that create a rich, textured look. The setting appears to be a deck or patio with wooden flooring and a railing in the background. This is the Retro Rainbow Blanket by Betty McKnit founder of 6-Day Crochet and creator of the viral 6-Day Kid Blanket and 6-Day Star Blanket. The yarn colors are extremely vibrant and follow a rainbow-like sequence. Prominent shades include: Pink Purple, in lavender and deeper tones, Blue in Light and Navy, Green in Lime and Grassy hues, A sunny and warm Yellow, Orange, and White used for the scalloped edge. Overall, the image conveys a cozy, inviting, and cheerful atmosphere—ideal for relaxing outdoors with a handmade touch of warmth and color.

Changing Colors

This pattern uses seven colors and changes colors at the end of every row. To change colors, draw the new color through the last two loops of the last stitch of the row. I suggest working your border rounds first and weaving in the yarn ends last. I do not recommend tying knots as they can and do come undone. Weaving in ends is time consuming, but if you’re planning to give your project away or sell it, give yourself the peace of mind knowing that your work will not unravel, and weave in all of your ends.

Carrying Yarns up the Sides of the Work

In the baby blanket version of this pattern, I gave instructions for floating the yarns up the sides of the work and working the border over them. I don’t recommend that technique for yarns heavier than DK.

Striping

The original 6-Day Kid Blanket stitches can take on many different looks depending on which rows the color changes fall on. If you would like to use this pattern variation with another 6-Day Kid Blanket stripe please see my article “No Two 6-Day Kid Blankets are Alike” for more information about the different 6DKB stripes and how to create them.
