Zig-Zag Crochet Baby Blanket – Free Pattern

by Doroteja

I am super excited to share this pattern with you. It has been on my mind for a while now and playing with my creativity, but I just could not get the hang of it. Every time I wanted to put it into stitches, stitch count didn’t match and the shape was off. The corners were usually too flat and the stitch pattern was more similar to waves then “mountains and valleys”.

Then it got this idea. Why don’t I use the technique I usually use with granny squares to get these perfectly shaped corners?

I got some yarn and tried it out, and I have to say it came out just the way I wanted. After so many trials and errors, I finally did it. Sometimes you just have to keep trying.

Today I am going to share with you a very simple beginner-friendly way how to crochet a zig-zag or chevron baby blanket. The main stitch we are going to be using will be good old double crochet stitch. I’ve included a step by step tutorial on how to make a double crochet stitch into my video tutorial, just in case you two are not best friends already.

The blanket is made of 9 color segments and each segment is made of 5 zig-zag rows of double crochet stitches. The first row is made into back bumps of the foundation chain which is a technique I use so both ends of the garment look exactly the same. With that, you get two loops on the top where you end your work and two loops at the bottom where you start your work.

I have to admit, I have been obsessed with this pattern, ever since I finished my first zig zag blanket. The pattern is super easy to remember, so you would be able to watch your favorite TV show or listen to your favorite podcast while crocheting in almost no time. The “mountains and valleys” are so symmetrical and beautiful. I just love it. Since then I finished 6 full crochet blankets and I am currently working on my blanket number seven.

The pattern comes with a video tutorial that you can find below and a PDF pattern available in my pattern shops on Etsy, Ravelry and Love Crochet that includes a few additional sizes of the blanket. I really hope you will like it as much as I enjoyed making this blanket.

Have a lovely crochet week and don’t forget to share your creations with me on Instagram using #crobypatterns. I can’t wait to see your blankets and give them a big Insta heart.

Crochet Baby Blanket – Zig Zag Blanket

I am will be using two shades of yarn for this blanket; beige and brick. Both of them are Aran weight yarns. The yarn is 100% cotton and it can get a bit heavy, especially if you are planning to make a larger blanket.

Therefore I would recommend Paintbox Simply Aran as a great substituting yarn. It’s 100% acrylic and it comes in a variety of beautiful modern colors.

I will call each segment of the pattern where you go up first and then down – one “mountain”. Each “mountain ” has a base and peak.

Our peak is CL 1 – cluster stitch 1 and our base of the mountain, with the exception of the first and very last segment of the round, is CL 2 – cluster stitch 2.

CL 1 – cluster stitch number 1 – increase
Also “peaks“ of our mountains. It’s simply made of 2 double crochet stitches, one chain and then two double crochet stitches again around the chain from the row below.

CL 2 – cluster stitch number 2 – decrease
Also “basis“ of our mountains. This is a stitch that joins together 5 stitches. Pick up 2 bases of double crochet stitches, then skip one stitch and pick up next two basis ob double crochet stitches. 

When you have all four bases on your crochet hook, yarn over and pull through all the loops on your hook. 

And that is the dc4tog with 1 skipped stitch in the middle.

Take some yarn in color brick and create a foundation chain made of 131 chains. Add 2 chains for the turning chain.

Note: If you would like to make a blanket bigger, add chains in a group of 22 (one full mountain – one up and down sequence). That will increase the size of your blanket for additional 12 cm or 4 3/4″. Make your blanket longer by increasing in in sets of 5 new rows. That will increase the length of your blanket for additional 9.5 cm or 3 3/4″.

Row 1: Start in the 2nd chain from the hook. Work 1 dc into the first one. Join next two with a dc2tog st. Work 1 dc into each of next 7. Repeat { CL1, dc 8, CL2, dc 8} 5 times. CL1. Dc 7. Dc2tog. Dc 1. Turn. = 133 sts.

Note: If you would like to have sharper tops of the “mountains “, try to ch 2 instead of ch 1 between two and two double crochet stitches in CL1.

Row 2: Ch 2. Start in the first. Dc 1. Dc3tog. Dc 7. Repeat {CL1, dc 8, CL2, dc 8} 5 times. CL 1. Dc 7. Dc3tog. Dc 1. Turn. = 133 sts.

Create three more rows with the same color, then switch to beige.

Create 5 rows with beige yarn.

Repeat 5 rows with brick and 5 rows with beige three more times.

End with 5 rows of brick color.

This means you have to have in total five sets made with color 1 (brick) and four sets made with color 2 (beige).

When you complete all the rows cut the yarn and fasten off. Hide all the yarn tails between the stitches. Make sure you are weaving them in under the stitches made with the same color.

Hi, I love this pattern! I was wondering if I keep repeating rows 1 and 2 alternating, or just row 2 only?

Doroteja October 25, 2022 - 10:58

Just row 2. 😊
