This rainbow crochet scarf is a perfect accessory to inject a little bit of color into the darker days of winter. The scarf only uses one stitch the so it is an absolutely perfect crochet pattern for beginners.

And while I decided to go for a rainbow color palette (I have a little girl who loves pretty much anything rainbow-related!) the stripe sequence is completely customizable so you can crochet a scarf to suit any age or taste.

Color Palette

The changing blocks of color help keep your interest even though the pattern itself consists of only one row repeat. I don’t know about you, but I really find that changing colors regularly gives me small little milestones to aim for, and before I know it I am finished!

For this project I used Stylecraft Special DK which is available in over 80 shades so you can really get creative with your stripe sequence on this scarf!

Since I used a DK weight yarn, the scarf does take a little longer than with a thicker yarn, if you’re looking for something you can make in an evening you might want to check out my Chunky Color Block Scarf pattern here.

However, this is still a perfect couch project, once you keep an eye on your row counts you can just crochet away mindlessly until it’s time to change color. And sometimes that is all that you want to do 🙂

Adjusting the Pattern


To make the scarf wider, adjust your starting chain by any number. Every 4 or 5 extra stitches will add about half an inch to the finished width. (Remember that the scarf is crocheted as a tube so your starting chain will be folded in half)


To make the scarf longer or shorter simply crochet more or less rounds as required. If adjusting the number of rounds remember to factor in this into your stripe sequence.

Stripe Sequence

To achieve a color block effect, this pattern has you changing colors every 20 rounds for the Child size and every 18 rounds for the Adult Size.

However, once you know your target number of rounds (see Finished Measurements above) you can do any stripe sequence that you wish.

Written Pattern

Abbreviations (US Terms)

ch = chain

st = stitch

sl st = slip stitch

sc = single crochet

blo = back loop only

Both Sizes: Child (Adult)

Foundation Chain:

Using C1, Make a slip knot and leave a long tail.

Ch 44 (54). Being careful not to twist the chain, join to the starting ch with a sl st to form a loop.


Ch 1 (does not count as a st), sc (blo) in the ch with the sl st (place a stitch marker in this sc), sc (blo) in each ch around until you reach the stitch marker (do not join to this first sc with a sl st) [44 (54)]


sc (blo) in marked stitch (now move the stitch marker to this sc), sc (blo) in each st around until you reach the stitch marker (again, do not join to the first sc) [44 (54)]

ROUNDS 3 – 20 (18):

Repeat Round 2

On the last st of Round 20 (18), change to C2

ROUNDS 21 – 200 (270):

Repeat Round 2 until desired scarf length is reached.

Child size: changing color every 20 rounds will give you 10 color blocks i.e. 2 blocks of each of your 5 colors

Adult size: changing color every 18 rounds will give you 15 color blocks i.e. 3 blocks of each of your 5 colors

Feel free to adjust the stripe sequence any way you like!

Fasten off and leave a long tail.


At both ends of the scarf, weave the tail in and out between the stitches of the first/last rounds. I weaved in and out approx. every 4 stitches.

Pull tail to close up the gap and add a couple of whip stitches to secure each end.

Sew on a pom pom at each end.

All done!
