The Cable Diamond Blanket, a Crochet Cable Baby Blanket to Love

Updated: 1 November 2026 by Sylwia (MyCrochetory)

This crochet cable baby blanket is for anyone who has ever looked at a cable knit sweater and thought, I want that, but with my hook. Fat cables twist and cross into diamonds all over it, and not a single stitch is knitted.

No cable needle, no knitting needles, no dropped stitches running down a column. Just front post stitches, rows of single crochet and a ribbed border you attach as you go.

Got a question halfway through, or want to show off your first diamond? Come say hi in my Facebook Group or Ravelry Group. I’m also on Instagram, Facebook and Pinterest.

From a cable pillow to a crochet cable baby blanket

This crochet cable baby blanket started with my Cable Diamond Pillow. I wanted those same cables and diamonds in something you can actually wrap a baby in.

A pillow mostly sits on the sofa and looks nice. A baby blanket gets dragged around, snuggled and washed, so it had to be soft enough for every day and pretty enough to keep for years.

As for cables, I’ve admired them on knitted sweaters and home decor for as long as I can remember. In crochet they looked hard to me, and that was exactly the reason I had to try them, because I can’t walk away from a challenge.

How crochet cables turn into diamonds

Each cable in this blanket is a front post stitch. You wrap a double or treble crochet around a stitch two rows below, and it pops up on the surface like a little rope.

The cross is where it gets good. Skip two post stitches, work the next two, then reach back for the ones you skipped, in front of them for one lean and behind them for the other.

Cross the ropes on the right rows and they open into diamonds, then close again. The plain single crochet rows in between give you a breather and keep the fabric thick and flat.

Front post treble crochet sounds much scarier than it is. My treble crochet tutorial walks you through the basic stitch and the front post version.

How hard is this crochet cable baby blanket?

I’d call this crochet cable baby blanket intermediate. If single crochet feels easy and you’re curious about post stitches, you’re ready for it.

The written rows are long, and yes, at first they look like a wall of text. Read them one chunk at a time and you’ll notice the same few moves coming back.

Keep an eye on your stitch count as you go. Each row ends with 126 stitches, and post rows split into 82 single crochet and 44 post stitches, so a slip shows up early.

The first diamond needs your full attention. By the second one, you already know what’s coming.

The ribbing comes first (yes, really)

This blanket starts backwards. Before any cables, you crochet one long strip of back loop single crochet, 8 stitches wide and 126 rows long.

Then you turn that strip sideways and work the whole main body into its edge. The other three ribbings join the blanket at the end with slip stitches, row by row, so you never sew a seam.

Ribbing joined as you go is my favorite way to finish an edge, because it looks neat from every side. My crochet ribbing tutorial has extra photos if you’ve never tried it.

The yarn for my crochet cable baby blanket

I crocheted mine in Scheepjes Bamboo Soft, and I still recommend it. The bamboo and cotton blend is smooth and soft, and every cable stands out sharp.

My color is Golden Nugget, a warm ochre gold. I’ve always loved ochre, and this blanket took 12 skeins of it, about 1968 yards.

Choosing your own yarn? Go for something soft, smooth and easy to wash, because fuzzy yarn blurs the cables. Bamboo Soft is also the yarn behind my Filip’s Blanket, an easier two-color baby blanket.

I wet block this blanket. Soak it, squeeze the water out gently, pin it flat to size and leave it to dry.

Love it, but your hook is busy with something else right now? Pin this crochet cable baby blanket and come back to it later.

Materials and tools

• Yarn: about 1800 m (1968 yd) of DK yarn. Shown in Scheepjes Bamboo Soft (50% bamboo, 50% cotton, 50 g = 150 m / 164 yd), colorway Golden Nugget (260), 12 skeins.
• Hook: 3.5 mm. Adjust the hook size if necessary to obtain the correct gauge.
• Notions: tapestry needle, scissors.

Level

Intermediate, because of the front post stitches and cable crosses.

Size

One size, adjustable: 95 x 70 cm (37.4″ x 27.6″) after blocking.

Gauge

21 sts x 24 rows = 10 x 10 cm (4″ x 4″) in sc, after blocking. Adjust the hook size if necessary to obtain the correct gauge.

Block your swatch the same way you will block your blanket before you measure.

Notes

• The pattern uses US terms.
• The blanket is worked in rows, back and forth. Ribbing 1 comes first, the main body is worked into its side, and Ribbings 2–4 are joined as you go.
• Ch1 at the beginning of each row doesn’t count as a st.
• All even rows are sc rows, worked in the sts 1 row below. All FPdc and FPtr are worked around the indicated sts 2 rows below.
• You always skip as many sts behind as you make post sts, so every row has 126 sts.
• The width is a multiple of 44 plus 38 sts. For a wider or narrower blanket, work 44 more or fewer rows in Ribbing 1. For a longer or shorter one, add or skip repeats of Rows 4–59.
• When a stitch is followed by a number, like sc14, work 1 sc in each of the next 14 sts. When a number comes before a stitch, like 2sc, work 2 sc in the same st.
• Instructions in […] are worked as many times as indicated.
• A different yarn weight changes the size and the yardage.
• The stitch chart is in the ad-free printable PDF. You’ll find the photo tutorial under each row below.

Stitches and abbreviations (US terms)

• ch – chain
• st(s) – stitch(es)
• sc – single crochet
• sl st – slip stitch
• BLsc – back loop single crochet
• yo – yarn over
• sk – skip
• rep – repeat
• RS – right side
• FPdc – front post double crochet. Yo, insert hook from front to back to front around the post of the indicated st, yo and draw up a loop, [yo and draw through 2 loops on hook] twice. Skip the st behind the FPdc.
• FPtr – front post treble crochet. Yo twice, insert hook from front to back to front around the post of the indicated st, yo and draw up a loop, [yo and draw through 2 loops on hook] 3 times. Skip the st behind the FPtr.

Crochet cable baby blanket FAQ

Is a cable blanket heavier than a plain one?

A bit heavier, yes. Post stitches use more yarn and build a raised, dense fabric, so pick a soft yarn that drapes well, like Bamboo Soft.

Can I make this crochet cable baby blanket bigger?

Yes, in both directions. Every 44 extra rows in Ribbing 1 add one more cable repeat across, about 8 1/4 inches, and every extra repeat of Rows 4–59 adds about 9 inches of length.

Which side is the right side?

Row 1 of the main body is the right side, and all the post stitches are worked on odd rows, so the cables always face you on the RS. Ribbing 4 also starts with the RS facing you.

How do I fix a cable crossed the wrong way?

Pull out the stitches back to that row and work it again. Post stitches come undone easily, and the photos under each row help you check every cross before you move on.
