Hello knitters!  I hope you all are doing well.  Today I want to share with you a pattern I am super excited about — the Rainbow Stripe Sweater!

Continue on to read about why I love this design and for a little background on the inspiration.  To skip ahead straight to the pattern links — scroll down!  Only want to learn how to add the stripes?  Check out the tutorial here.


Behind the Design

This is one of those patterns I had in my mind for so long before I actually put it all together.  I have always loved the color pop, rainbow styles of the 70s and 80s and wanted to tie it all together with a unique detailing.  I knew I wanted to keep the shape of this sweater simple — relaxed fit, the slightest crop, and almost a ‘sweatshirt’ style feel using Comfy Cotton Bled yarn.


Tips and Tricks

One of the biggest questions with this sweater was how I would work the stripes.  In knitting, horizontal stripes are tough to do.  You mostly need to use either color work techniques or a stitch duplication.  I took the stitch duplication a bit further and made a little appliqué stripe using a crochet hook.  Don’t be afraid — this technique is SO easy and if you are able to knit a sweater I promise you will be able to add these stripes 🙂

Choosing the Perfect Size

As I mentioned earlier, this pattern was designed to have a relaxed fit — almost like a favorite sweatshirt!  I also wanted to add a bit of vintage appeal by making it slightly cropped.  But don’t worry,  I’ve added places throughout the pattern where length can be added or subtracted to get the perfect fit for YOU!

XS (S, M, L) (XL, 2X, 3X)

Finished Width at Chest:  18 (20, 22, 24) (26, 28, 30)”

Finished Chest Circumference:  36 (40, 44, 48) (52, 56, 60)

Finished Length:  21 (21.5, 22, 22.5) (23, 23.5, 24)

Sleeve Length:  17 (17.5, 18, 18) (18.5, 18.5, 18.5)

My recommendation would be to choose a size that is 6-8” larger than your corresponding body measurements.  For example, I am wearing size S and have a bust measurement of 34” so I wearing this sweater with 6” of positive ease.

Another thing I love about this sweater is that you can use scrap yarn for the stripes — I always have these beautiful little scraps left over but nothing to do with them!  You can also mix up the colors you use in the stripes.  I black stripes would be awesome.  I used Vanna’s Palettes in Happy from Lion Brand Yarn but you can use any colors or yarn you want — just be sure to keep the colors within the stripes similar yarn weight to the sweater.

  1. Hi there! I’m knitting this and have come to the point where I’m separating the sleeves and the body. Right before that part it says to knit rows 21-22 until piece measures 10.5 inches from CO at back of neck. Is it 10.5 from where I joined in the round or from the longest point on the other side? Thank you!

  2. I wanted to buy this as a kit, but the colored yarn is no longer available, so it will not add to my cart. Will you ever include the complete pattern on your website instead?

    1. Aw that’s a bummer, it must have sold out! The pattern itself is available on Ravelry or my Etsy shop
