Easy Chunky Crochet Blanket Pattern: Free Spike Stitch Throw

If you’re looking for an easy chunky crochet blanket pattern with plenty of texture, this Spike Stitch Blanket is a great project to add to your list. The repeating stitch pattern is easy to memorize and creates beautiful rows that really stand out when worked in multiple colors.

After seeing how much everyone enjoyed my Braided Puff Crochet Blanket earlier this year, I wanted to design another cozy blanket with a completely different look and texture. This time, I chose the spike stitch—a simple technique that creates bold stripes and a beautifully textured fabric without adding a lot of extra complexity.

Made with size 6 super bulky yarn, this blanket works up quickly while still feeling soft and comfortable. The pattern includes instructions for both a baby blanket and throw size, and it’s easy to customize the width and length to fit your needs.

Whether you’re making a blanket for your own home, a thoughtful handmade gift, or something to sell at fall craft markets, this pattern is a relaxing project you’ll be reaching for again and again. Grab your favorite color combination, and let’s get started!

Yarn Requirements For The Spike Stitch Blanket

The Spike Stitch Blanket Pattern is written using size 6 super bulky blanket yarn. I prefer Lion Brand Re-Spun Thick & Quick. Below are the specific suppliers I highly recommend for sourcing your supplies:

Colorways & Yardage Specifications

Color Breakdown & Sizing SpecsBaby Blanket SizeFull Throw Size
Color A (Whipped Cream)480 yards (3 skeins)865 yards (4 skeins)
Color B (Hazelwood / Desert Sand)115 yards (1 skein)200 yards (1 skein)
Color C (Dark Cherry / Squash)115 yards (1 skein)200 yards (1 skein)
Color D (Cider / Cinnamon Stick)115 yards (1 skein)200 yards (1 skein)

Yarn Alternatives

You are more than welcome to experiment with different yarns! Just keep in mind that your gauge and finished blanket weight may vary depending on the fiber content and yarn thickness.

I specifically chose Lion Brand Re-Spun Thick & Quick because, although it is classified as a size 6 super bulky yarn, it is lighter in weight than many other options in that category. Some super bulky yarns can make a finished blanket feel quite heavy.

Lion Brand Wool-Ease Thick & Quick would also work beautifully as an alternative option, but please note that the finished blanket may turn out slightly denser and heavier.


Sizing For The Spike Stitch Blanket

The Spike Stitch Blanket Pattern is offered in two popular sizes. Below are the approximate finished dimensions for each version:

Blanket Sizing OptionsApproximate Finished Dimensions
Baby Blanket Size32″ Ă— 48″ inches
Chunky Throw Blanket Size48″ Ă— 58″ inches

To adjust the overall width of your blanket, simply increase or decrease the number of your beginning chains. Your foundation chain should always be worked in multiples of 2.

To adjust the final length of your blanket, continue working the pattern row repeat as many times as needed until you reach your desired length measurements.

Example: If your goal is to have exactly 61 stitches in Row 1, you will need to chain 62 to start your project.

Gauge

6 rows x 8 hdc = 4 Inches with M Hook
Please be sure to check your gauge before starting, as tension can vary greatly from person to person and depending on the yarn used.

How to Crochet the Special Stitches for This Pattern

Back Hump or Bump of Chain

The back hump (also known as the back bump) is located on the backside of a crochet chain. While the front of the chain looks like a row of “V” shapes, with a front and back loop, the back features a small bump or bar behind each “V”. To locate the back hump or bump, slightly rotate the chain or chains toward you. 

Spike Double Crochet (spdc)

A spike double crochet is an elongated double crochet worked into a lower row/round, usually one or two rows below the current one.The lower you go, the longer the stitch. In this pattern we’ll be working in one row below.

  • Step 1: Yarn over, insert your hook into indicated stitch, 1 row below the current row.
  • Step 2: Pull up a long loop to the same height as your current row.
  • Step 3: Yarn over and pull through 2 loops, yarn over and pull through remaining two loops (just like a regular double crochet).

Herringbone Half Double Crochet (hhdc)this st is for the border only

Yarn over, insert your hook, yarn over, pull up a loop and pull directly through the first loop on your hook.  Yarn over and pull through the remaining two loops. 📺 Watch the Step-by-Step Video Tutorial on YouTube Here

Free Chunky Crochet Blanket Instructions — All Sizes

Before starting your foundation chain, review these quick construction parameters:

  • Change colors by pulling the new color through on the last yarn over of the final st of the previous color, and fasten off after each color change.
  • You can use as many contrasting colors as you’d like; however, the spdc pattern shows best if you change colors every two rows.
  • When two numbers are shown, the first refers to the Baby Blanket and the second refers to the Throw Blanket.

Example: Ch 62(92) means ch62 for the Baby Blanket or ch92 for the Throw Blanket, and (61, 91sts) indicates the stitch count for each size.

Color A

Row 1 RS. Ch 62(92), working in back humps, hdc in 2nd ch from hook and remaining chs across, turn. (61, 91sts)
Rows 2-8. Ch1, hdc in each st across, turn. (61, 91sts)

Color B

Row 9 RS. Ch1, *dc in next st, working in one row below, spdc in next st, repeat from * across, ending with a dc in last st, turn. (61, 91sts)
Row 10 WS. Repeat row 2. (61, 91sts)

Color C

Row 11. Repeat row 9. (61, 91sts)
Row 12. Repeat row 2. (61, 91sts)

Color D

Row 13. Repeat row 9. (61, 91sts)
Row 14. Repeat row 2. (61, 91sts)

Color A

Row 15. Repeat row 9. (61, 91sts)
Rows 16-22. Repeat row 2. (61, 91sts)

Repeat Section Rows 23-78 (baby) or 23-92 (throw)
Repeat Rows 9-22 a total of 4x for baby blanket (5x for throw), following the established color sequence.

Note: Your final row should end on the WS of the blanket. Do not fasten off, continue to border instructions below.


Border

  • If you’re having trouble inserting your hook into the row ends, go down one hook size.
  • Make sure you turned your work after the last row, so the RS of the blanket is facing you.
  • Starting in the corner where you left off, ch1, work 3hhdc in the corner.
  • When working into the row ends, insert your hook under one loop only rather than around the entire row end. This creates a neater edge.
  • Evenly hhdc around the entire perimeter of the blanket, placing 1hhdc in each hdc row end, 2hhdc in each dc row end, and 3hhdc in each corner.
  • Join to the beg hhdc using an invisible join (instructions below).

Invisible Join: After completing the last stitch of the border, fasten off. With a tapestry needle, weave the yarn under both loops of the first stitch, then back through the back loop of the last stitch to create an invisible finish.

Finishing Your Blanket

Fasten off and weave in loose ends. Your blanket is complete! It should not require blocking, though a light steam block may be desired. Enjoy!!
